1. Introduction

London Stock Exchange Derivatives Market (LSEDM) offers trading of Equity and Interest Rate derivatives products.

Equity derivatives products include single stock, index and dividend derivatives based on United Kingdom, International Order Book (IOB), Norwegian and Turkish underlyings.

Interest Rate derivative products developed in conjunction with CurveGlobal include Short Term Interest Rate (STIR) futures on Three months Euribor® and Sterling and Long Term Interest Rate (LTIR) futures on Schatz, Bobl, Bund and Long Gilt. CurveGlobal is an interest rates derivatives joint venture between London Stock Exchange Group and a number of major financial institutions

LSEDM’s trading platform is hosted in the data-centres of the London Stock Exchange Group (LSEG) and has interfaces common to other markets of LSEG, ensuring that customers accessing other LSEG markets can connect to LSEDM with minimal incremental cost or effort.

LSEDM offers Member Firms new and innovative features, in addition to the highly successful market models used for its existing Norwegian and IOB business which has been developed alongside Members.

Two different instances of the platform are currently run, based on SOLA: one for Equity derivatives and one for Interest Rate derivatives.

Clearing and margining 1.1.

Member Firms can improve operational efficiency and net margin payments across geographies, all through one clearer - LCH.Clearnet (LCH).

For equity derivatives, EquityClear members can benefit (with the exception of Norwegian contracts due to interoperability arrangements) from margin offsets and cross source trade netting.

For Interest Rate derivatives, LCH clearing members will be offered portfolio margining services between listed derivatives and OTC derivatives cleared by LCH SwapClear services. In order to benefit from portfolio margining, Clearing Members must be a member of both SwapClear and Listed Derivatives services under the same legal entity.

Strike Price Generation 2.4.

LSEDM generates new strikes on Options series according to the following:

Minimum number of series in-the-money (ITM);

Minimum number of series out-of-the-money (OTM);

Always one series at-the-money (ATM).

2.4.1. Designation of the ATM strike

Every minute, the SOLA derivatives system marks one of the series listed the “ATM” strike price. It does this by looking at the price of the underlying and seeing which series is closest to this level.

At the end of each day, an ATM strike is chosen (or created if it is the night before the listing of a new series) relative to the closing price of the underlying.

New In-the-Money strikes and Out-of-the Money strikes are generated relative to this ATM price.

The ATM strike for a particular underlying / expiry combination will be created at a level determined



9

by the strike price increment for that expiration. For example, if the strike price generation increment for a particular underlying/expiry combination is 25 index points, the ATM series will be created / chosen at a price ending in 25 points, 50 points, 75 points or 00 points. If the generation increment is 50 points, the ATM strike will be created / chosen at a price ending in either 50 points or 00 points.

2.4.2. On Request listing of additional standardised series

Members may request by phone or electronic communication to LSEDM Market Operations for a specific equity options series to be listed on the Order book if it is not automatically generated in accordance with the parameters described in the relevant Contract Specifications and the Strike Price Generation section of the Trading Services Description. This is known as an ‘On Request’ listing.

Members shall provide the following information:

The Underlying instrument;

The Expiration Month, which should already exist on screen, (Expiration Day will always be standardised as per the relevant Contract Specification)

The Strike Price (should be within the same strike price interval that already exists).

LSEDM Market Operations will confirm when the ‘On Request’ Standard series is available for trading on the Order book.

3. Trading Functionality

The key features of the LSEDM trading platform are described in this section. Please refer to Appendix A for a detailed description of trading phases across products traded on LSEDM.

Opening auction (available for interest rate 3.1.derivatives only)

Opening auction phase on interest rate derivatives is structured according to the three following states.

a. Pre-Opening (from 6:30am to a specific time set at each product level)

Orders entered during this phase contribute to Theoretical Opening Price (TOP) calculation. No trade execution is performed during this phase and Member Firms are only allowed to enter, modify and cancel orders and quotes (cross orders and strategy orders are not available).

SOLA notifies all clients via HSVF with one message for each Instrument Group that switches to the Pre-Opening state. In case there is one bid and one ask at the same price in the orderbook during the Pre-opening state or Instrument in the reserved status

3:

the first level displays the TOP as an aggregated price level

if there are market orders in the orderbook, the TOP level is split as follows: o the side(s) of the orderbook with market

order(s) contributing to the TOP level displays the aggregated market order price(s) in the second level

o subsequent level display aggregated limit order(s) contributing to TOP

3 “Reserved status” of a Instrument refers to an intra-day

auction.

subsequent levels display the additional prices that would not match TOP.

Theoretical Opening Price calculation

TOP is calculated and disseminated in real-time. In particular, TOP calculation is based on the following steps:

Step 1: Maximisation of traded volume

TOP is the price at which it is possible to execute the highest number of contracts.

Step 2: Minimisation of surplus

If there are several prices available after Step 1, TOP will be equal to the price that leaves the minimum non-tradable quantity in the orderbook, in relation to both buy and sell orders with prices equal or better than TOP.

Step 3: Minimisation of variation against the last traded price / reference price

If there are several prices left after Step 2 and many of these prices are left without a surplus, Step 3 will define a tradable price range and determine TOP within that range, minimizing the variation against the last traded price, if available, or the reference price, if the last trade price is not available.

In particular, with regards to tradable price range determination, if multiple prices are left after Step 2, the system defines a range of valid opening prices based on the following rules:

if the market unbalanced quantity includes market orders, the range is set at the best limit order on the same side up to the instrument limit price (please note that the price must respect both Step 1 and 2). If best limit order price does not maximize the traded volume or minimized the unfilled quantity, then TOP range start at the first price meeting Step 1 and 2 criteria;

if the market unbalanced quantity includes limit orders:


14

o if buy is the unbalanced side, then the range lower boundary is determined with the highest buy limit order that would remain unfilled at TOP price (included in the unbalanced quantity);

o if sell is the unbalanced side, then the range higher boundary is determined with the lowest sell limit order price that would remain unfilled at TOP price (included in the unbalanced quantity).

If at opening, an instrument series has no last trade price and no reference price or it is set to 0 and the Pre-Opening book shows only market orders on both sides, the instrument series will be set to “reserved” status.

The following example illustrates the definition of a price range:

Reference Price = €1.25

Orderbook during Pre-Opening phase

Buy Sell

Order # Quantity Price Price Quantity Order #

1 100 MKT €1.05 50 1

2 50 €1.00

the initial price range is €1.05 (Order 1 on the Sell side) to infinite (the market order (MKT) on the Buy side)

the engine validates the price if the Reference Price is located within the range

if the reference price is €1.25, the opening price will be set at €1.25

the remaining quantity of the market order will be booked at €1.25

b. Validation (Immediate)

The Trading System does not accept any more new orders or modification/cancellation of existing ones and verifies the validity of TOP according to specified price limit variations.

c. Opening (Immediate)

For each Instrument Group that switches to the Opening state, SOLA notifies all Member Firms and data vendors with one message.

If last TOP is validated, trades for each instrument series are executed at that price, otherwise a volatility auction starts with each series assigned the “reserved” status.

Order book Trading 3.2.

LSEDM’s Order book operates different matching algorithms on a product-by-product basis: i) Price-Visibility-Time priority, and ii) Pro-rata matching. A summary of the matching algorithms applied to each product traded on LSEDM is given in Appendix B. All executed trades on the LSEDM Order book will contribute to price and quantity updates in the Market Data Feed (HSVF).

Please refer to Appendix A for a detailed description of trading phases across products traded on LSEDM. Section 6 (Risk Controls) of this document describes controls applicable to LSEDM.

3.2.1. Order Types

Orders of the following type may be placed by Members:

by Price type: limit order, market order, top order, stop (loss) order, if touched order;

by Quantity type: minimum quantity order, iceberg order (iceberg orders not available for Interest Rate products);

by Duration type: day order, good till day (GTD), good till cancelled (GTC), immediate order (FAK/IOC), while connected order.

For a full list of Order Types and availability of such order types depending on the applied matching algorithms, please see Appendix C.


15

3.2.2. Placing and Cancellation of an Order

On placing an order by way of the Trading System, a Member shall provide the following information:

the Series, Type / Style, Class and the Listed Product in question;

the Expiration Month;

whether its order is to buy or to sell;

in case of an Options Contract, whether it is a Call or a Put;

the price for the order;

the order's volume;

whether it is a Limit order, Market order or a Combination order;

the Account to which the transaction, if executed, is to be allocated;

if appropriate, the identification code of the Client for whom the order has been placed.

On placing an order into the orderbook, Members should ensure that the value of the order does not exceed the maximum permitted size for the Contract in question, Members should note that any order placed on the orderbook which exceeds the applicable maximum permitted size shall be rejected. Members will receive a message stating this. Price and Quantity restrictions are detailed in Appendix D. The Tick size applicable for trading on the orderbook is described in the relevant Contract Specification.

An order will remain valid and effective until an instruction to cancel is given by the Member which placed the order, or the order automatically expires as defined by its Duration type parameter. A Member may contact Market Operations to cancel an order entered on the Trading System with the relevant order details (instrument, price, quantity, time etc). Members wishing to remove all their orders from the orderbook in one go should contact Market Operations, who can perform this action. Such requests must always be made by a Registered Person.

3.2.3. Modification of an order

Unless cancellefd, an order will remain valid and effective until an instruction to modify is given by the Member which placed the order.

a. Products based on Price-Visibility-Time priority algorithm

Under the Price-Visibility-Time priority model, any modification of an Order involving its price or a volume increase is treated as the cancellation of the original Order and the submission of a new Order. Time priority of such Order shall be determined by reference to the time at which the modified Order is entered on the orderbook.

Where the Order modification involves only a reduction in its volume, the ranking of original Order is not affected.

Modification Price priority Time priority

Quantity decrease

Maintained Maintained

Quantity increase*

Maintained Lost

Price change* Lost Lost

*results in deletion of original order and entry of a new order

with new price time priority and associated order number

b. Products based on Pro-Rata priority algorithm

Under the Pro-Rata model, any modification of an Order involving its price or an increase in the volume of an Order is treated as the cancellation of the original Order and the submission of a new Order.

For “Progressive” and “Age” Pro-rata algorithm (see Appendix B), the timestamp used to determine the weight attributed to the time priority of such Order shall be determined by reference to the time at which the modified Order is entered onto the orderbook.


16

Where the order modification involves only a reduction in its volume, the ranking of the original order is not affected when the “Progressive” Pro-rata algorithm is implemented. Note however that priority would be lost under the “Age” pro rata algorithm and any modified order will get a new timestamp effectively putting it to the back of the queue.

The “Best Price Setter” attribute of an Order, where applicable (see Appendix B), is re-evaluated at any modification of the order, except in case of quantity reduction for Order that already gained “Best Price Setter” status.

3.2.4. Cancellation on Disconnection

Members should be aware of the following:

o When conducting the login procedure, SOLA allows for the Member to specify an “inactivity interval” which indicates the number of system “heartbeats” that must be missed before the Member is considered disconnected. If the inactivity interval is set to “0” then the user is never considered to be disconnected;

o In case of member disconnection due to technical issues, all orders with Duration type parameter “While Connected” will be cancelled. Please note that “Good Till Day” and “Good Till Cancelled” orders will not automatically cancel on disconnection.

LSEDM therefore strongly recommends the use of “While Connected” orders for Members that are concerned about cancellation on disconnect.

3.2.5. Bulk Quoting (product dependent)

Members that have conformed to the LSEDM SAIL API are also able to send Bulk Quotes to the LSEDM orderbook through Bulk Quote Trader IDs. Bulk quotes may contain up to 280 separate quotes with LSEDM validating each quote within the message. Throttles apply as per rates described in the SAIL technical specification. Bulk Quoting is a more efficient way of sending quotes to the Trading System as only a single message is required as opposed to multiple cancellations and resends of order messages.

Bulk quotes are only valid for the current trading day and not available for strategies. Members can remove quotes on disconnection by sending the Disconnection Instruction message. It is not possible to amend an existing Bulk quote; any changes have to be made by cancelling the existing Bulk quote and replacing it with a new quote, which results in a loss of time priority.

Protections for Members using Bulk Quoting are described in Section 6 (Risk Controls).


17

Before the Opening, an “Intervention Period” allows bulk quote users to enter Bulk Quote data which would be used to retrieve the quote ID. The Intervention Period is only available for specific products. Members can continue to cancel orders during this period.

A specific global cancellation message, applying only to quotes placed using the Bulk Quote message, can be sent by Bulk Quote users and will pull all quotes related to a specific trader on all instruments in the same class. The Trader ID and instrument Group ID are used to specify which quotes to cancel. Orders which are not entered using Bulk quotes will not be cancelled.

3.2.6. Obligations for Market Makers

Firms registered as Market Makers in a certain instrument class will have to meet a set of market making obligations that are monitored by LSEDM.

Market Makers should note the following:

for Equity derivatives, Market Makers are requested to comply to their market making obligations by sending quotes via the Bulk Quote message in the SAIL API;

for Interest Rate derivatives, Market Makers are requested to comply to their market making obligations by sending either orders or quotes via the Bulk Quote message in the SAIL API.

LSEDM reserves the right to terminate the Market Maker Agreements if the Member fails to meet its obligations. LSEDM also reserves the right to withhold or cancel any incentives, including any revenue share, in the event that the Member fails to meet its obligations or terminates its Agreement early.

For further information with regards to Market Making obligations, please refer to the Market Making Obligations document on the LSEDM Document Library.

3.2.7. Request for Quote (RFQ)

Request for Quote (RFQ) allows any Member to broadcast a message to the whole market in a particular instrument via the HSVF market data feed. Market Makers, as part of their agreement with LSEDM, have an obligation to reply by entering a quote in to the orderbook for that specific instrument.

RFQ contains:

o Instrument Class;

o Instrument ID Code;

o Quantity (not mandatory).

3.2.8. Strategy instruments

a. Exchange generated strategies (standard combinations)

For orderbook traded products, LSEDM automatically makes available for trading a pre-defined set of strategy instruments.

Please refer to Appendix F for the list of available standard combinations and their related characteristics.

b. User generated strategies (flexible combinations)

On all orderbook traded Futures and Options, LSEDM has enabled SOLA functionality that allows users to create their own strategy instruments and list them on the orderbook as standalone products available for trading by other Member Firms.

Derivatives strategy trades can be executed via both “Strategy v.s. Strategy” and “Strategy v.s Legs” functionality. Where a Strategy Instrument can be executed against another Strategy Instrument, the trade will be executed on the terms of the matching Strategy Instrument provided that it is not possible to execute the Strategy against Legs on the orderbook on better terms.




18

A strategy can have a maximum of four legs. Each leg of the strategy must: (a) contain instruments with the same contract size, and (b) have legs that appear in natural number ratios, i.e. as multiples of the smallest leg size in increasing order

4. Market

participants will need to enter the net price of the strategy i.e. the sum of the price of each leg. SOLA automatically validates the price and quantity before allowing completion of the execution. Strategy instruments interact with Circuit Breakers. Trades executed in Strategy instruments contribute to price and quantity updates to the Market Data Feed (HSVF).

A strategy may be placed as either a Limit order or a Market order. See Appendix C for more details.

Using dedicated messages available within LSEDM’s SOLA APIs, developers can create front-end solutions with pre-configured strategies. For further details, please see the LSEDM Technical Documentation (SAIL Specification and FIX Specification).

For further information on strategies, please refer to the “Strategies” documentation on the LSEDM Document Library.

Tailor-made (Flex) series (for equity 3.3.derivatives only)

3.3.1. Tailor-made (Flex) series creation

LSEDM allows for participants to create Tailor-made (Flex) derivative series in the trading platform intra-day, and to report Block Trades on them. These series will be Hidden (not disseminated via HSVF as public Reference Data) and only visible to the participant that created them. Participants will be able to retrieve ISINs for Tailor-Made (Flex) derivatives through the Clearing

4 If market participants wish to enter a strategy with derivatives

based on different underlyings / contract sizes, they may use the Bundled Order functionality - please refer to para. 3.4.2. of this document.

System (BCS Application) or through secure FTP in Excel or CSV report formats.

Member Firms will be able to create Tailor-made (Flex) series specifying the Underlying, Expiry Day/Year, Strike (only for Options), Option Style (only for Options), Instrument Type (call/put, only for Options) and Delivery Type (cash vs physical).

Tailor-made (Flex) series will remain active until the expiration date specified at the moment of the instrument creation. Participants will not be able to create Tailor-made (Flex) series with same characteristics of an existing Standard instrument.

3.3.2. Conversion of Tailor-made (Flex) series to Standard series

When LSEDM trading platform automatically generates a Standard series with the same parameters of a Tailor-made (Flex) series (e.g. due to the generation of new expiries, or new strikes due to movement of the underlying security), the trading platform automatically converts Tailor-made (Flex) series to Standard series.

The new Standard series inherits the same ISIN as original Flex series. The series will become public and instrument data will be disseminated via HSVF as public Reference Data.

Bilaterally Negotiated Trades (BNTs) and 3.4.Trade Reporting

A Bilaterally Negotiated Trade (BNT) is a privately negotiated transaction that is a Block Trade, an Exchange of Futures for Physicals (EFP) or a Exchange of Futures for Swaps (EFS).

Bilaterally Negotiated Trades may be trade reported to LSEDM during the times laid down in the Contract Specifications.

Trade reporting can take place via direct entry by the Member into the SOLA platform using available functionalities and/or, where permitted, through a manual process using pre-defined templates

19

available on the LSEDM Derivatives Trade Reporting section.

For manual trade reporting, a BNT trade report shall be sent to the LSEDM Market Supervision team via email at [email protected] and contain the following details:

o the type and class of a Standard or Tailor-made Contract;

o the term, if a Tailor-made (Flex) Contract;

o the Strike Price;

o the Option Style (if applicable);

o whether it wishes to buy or to sell;

o the name(s) and account(s) type of the Counterparty(ies)

o Settlement type (if applicable)

o Type of underlying (if applicable).

Subject to LSEDM Market Supervisons review of the template each side of the trade will be registered and Counterparty(ies) will be promptly informed of acceptance.

Through secure FTP in Excel or CSV formats, Member Firms are able to receive reports containing ISIN information of a BNT manually reported to aid FCA Transaction Reporting. Please contact Market Operations for further information.

Trades Reports in Standard series are always published. Block Trades must comply with the requirements including size and price controls outlined in section 6.2 and Appendix D. EFP/EFS transactions must comply with the price controls outlined in section 3.4.4.

Trade Reports in Tailor-Made (Flex) series will not be published thus remain Hidden and will be subject to a reasonable theoretical price validation by LSEDM Market Supervision prior to acceptance.

Chapter 5 of the LSEDM Rules (“Bilaterally Negotiated Trades and Trade Reporting Rules”) details BNT and Trade Reporting rules.

3.4.1. Block Trades

A Block Trade is a BNT which is permitted to be executed away from the order book in a quantity that meets a minimum volume threshold.

A Block Trade can be executed between two different Members (aka “committed cross”) or with a single Member acting on both sides of a trade (aka “internal cross”).

Block Trading is available for Standard series or Tailor-Made (Flex) series, with the guarantee of CCP Clearing with LCH. Block trades in Standard series contribute to price and quantity updates to the Market Data Feed (HSVF). Block trades in Tailor-made (Flex) series remain hidden and only visible to the participant involved in the trade.

Block trades (in either Standard or Tailor-made (Flex) series) must be:

above a minimum volume threshold;

within certain price and risk control parameters, for example the bid/ask or reasonable theoretical price (pre-trade or post-trade, depending on the product and size);

consistent with the minimum tick increment (please refer to tick increment table in the HSVF technical specification on LSEDM Document Library).

A summary of Block order types, and key information on each, is given in Appendix C.

A summary of minimum block thresholds and price controls on a product basis is provided in Appendix D. Further information on Risk controls is provided in Section 6.

3.4.2. Bundled orders (Block trades with multiple legs)

LSEDM facilitates the grouping of multiple Block trades into a unique window through the Bundled order functionality. This functionality offers certainty of simultaneous execution of all the

http://www.lseg.com/derivatives/lsedm-trade-reporting

http://www.lseg.com/derivatives/lsedm-trade-reporting

mailto:[email protected]




20

individual legs included in the Bundled order, or no execution at all.

The functionality is highly customisable, allowing market participants to create their Bundled orders with the same or different counterparty and same or different financial instruments in each leg, and an individual price for each leg.

The Bundled order functionality offers an alternative to the Strategy functionality on the LSEDM platform, whilst providing additional flexibility as described below.

Through the Bundled order functionality:

traders can enter a Bundled order in up to 4 legs;

traders can independently specify for each leg of the Bundled order:

o financial instrument (e.g. Option or Future), including Standard and/or Tailor-made (Flex) series;

o price and size;

o Counterparty(ies);

o buy or sell.

the same Trader ID must be used for each leg of the Bundled order.

Once the Bundled order is entered, each counterparty will receive a notification message. On receipt counterparties will be able to submit acceptance of its Leg of the Bundled order, or reject it.

In case of rejection from one of the counterparties, acceptance by any other counterparty of the Bundled order will be prohibited. Pending legs will remain in the system till the daily close of the Block Trade facility (i.e. end of orderbook trading hours and/or of extended period of time where applicable) until they are all accepted.

The Bundled order will be registered and sent to clearing only on acceptance of all of the counterparties.

Block trade price and quantity validations are also applicable.

For further information on Bundled orders, please refer to the specific product documentation available on the LSEDM Document Library.

3.4.3. Third Party order execution (Block trades for Reporting Brokers)

LSEDM allows for Members registered in the capacity of Reporting Brokers to initiate electronically the execution process for a Block trade through the Third Party order execution functionality.

This is an alternative to the manual Trade Reporting process, as detailed in paragraph 3.4.

Through the Third Party execution functionality, Reporting Brokers are able to submit a trade as a Block Trade or Bundled order for either Standard or Tailor-made (Flex) series which has been executed between multiple counterparties:

Reporting Brokers can enter a Third Party trade with up to four legs;

Reporting Brokers must independently specify for each leg of the Third Party order:

o financial instrument (e.g. Option or Future), including Standard and/or Tailor-made (Flex) series;

o price and size;

o counterparty(ies);

o buy or sell.

Once the Third Party order is entered by the Reporting Broker, each counterparty will receive a notification message without disclosing the names of the other counterparties (only the name of the Reporting Brokers will be visible).

On receipt, the counterparties will be able to submit acceptance of its own leg of the Third Party order, or reject it.



21

In case of rejection from one of the counterparties, acceptance by any other counterparty of the Third Party order will be prohibited.

Pending legs will remain in the system till the close of the Block Trade Facility until they are all accepted. The Third Party order will be registered and sent to clearing only on acceptance from all counterparties.

Upon registration and clearing, Members will receive a confirmation of the deal and counterparty IDs will be visible.

Block Trade price and quantity validations are also applicable.

To register as a Reporting Broker and enable access to the Third Party Execution functionality within SOLA, please contact [email protected].

Reporting Brokers may also utilise the services of approved LSEDM Reporting Broker Platform Providers (RBPPs) to submit Third Party Executions to SOLA.



22

3.4.4. Exchange of Futures for Physical (EFP) and Exchange of Futures for Swaps (EFS)

EFP and EFS trades must be trade reported via pre-defined templates submitted by email. An EFP/EFS trade consists of the simultaneous execution of an equity or interest rate derivatives contract (contract leg) against an offsetting equivalent amount of the Related Position Leg, such as underlying physical asset/forward (EFP) or OTC swap (EFS).

EFP/EFS trades can be submitted provided that the LSEDM required conditions are satisfied, among which:

the price is reasonable in light of the commercial circumstances of the buyer and the seller as well as consistent with related price controls

5. In addition, the price of the listed leg

must be also consistent with the minimum tick increment for the related equity or interest rate derivative;

the position leg must bear reasonable equivalence in terms of physical and/or economic properties with the underlying of the relevant contract leg, including price correlation. Upon the request of LSEDM, Members must provide a justification as to how the related position is deemed equivalent;

5 The Exchange applies price controls at +/- 20% from the BBO

in the orderbook at the time the EFP or EFS is reported. In cases where there is no BBO in the orderbook at the time the EFP or EFS is reported, the Exchange may use +/- 20% from the last BBO in the orderbook as a guide although discretion will be applied in appropriate cases.

the quantity of the Listed Leg may be any whole number quantity of a Listed Product up to the maximum order size, provided that the quantity of the Related Position Leg is broadly equivalent to the quantity represented by the Contract when considered in light of the overall economic exposure between the two legs;

EFP/EFS trade report must be submitted within one hour of execution.

Additional information on EFP/EFS transaction’s procedure are provided in the “London Stock Exchange Derivatives Market Bilaterally Negotiated Trade Guidance" document.

3.4.5. BNT cancellation

Requests for cancellations of BNT trade reported through a SOLA functionality and/or, where permitted, a manual process using pre-defined templates should be made to LSEDM Market Supervision, in accordance with the procedure and timings as per Chapter 5 of the Rules, available on the LSEDM Document Library.

5. Market Operations and Clearing

Transaction reporting and Market Identifier 5.1.Code (MIC)

Every unique series on LSEDM has an associated ISIN code. This ISIN is a unique identifier that can be used for transaction reporting purposes.

Each series can also be identified by its unique series level code, described in the Section 2.1.1 (symbology).

When LSEDM trading platform automatically generates a Standard series with the same parameters of a previously created Tailor-Made (Flex) series with a standard expiration (due to the generation of new expiries, or new strikes due to movement of the underlying security), the trading platform automatically converts the Tailor-Made (Flex) series to Standard series. The new Standard series inherits the same ISIN as the original Tailor-Made (Flex) series. Series will then become public and instrument data will be disseminated via HSVF as public Reference Data.

The Market Identifier Code (MIC) for LSEDM is XLOD, while the Exchange ID is:

“E” for Equity derivatives;

“R” for Interest Rate derivatives.

LSEDM uses the LEI for London Stock Exchange Plc: 213800D1EI4B9WTWWD28.

Central Counterparty Protection 5.2.

All Future and Option Contracts traded or reported on LSEDM will have LCH acting as Central Counterparty.

At the point of trade registration, trades are novated to LCH, whereby LCH becomes the long position against the short counterparty to the trade, and the short position against the long counterparty to the trade.

Margining and Position Controls 5.3.

5.3.1. Equity derivatives

For Equity derivatives, initial margin is calculated and collected by LCH using London SPAN V 4.0. There are three major inputs to the London SPAN margin calculation, Positions, Prices and Parameters (determined by LCH and reviewed on a regular basis). Any change to any one of these parameters will result in a change to the margin requirement. Please refer to the SPAN parameters on the LCH website.

LSEDM calculates daily variation margin of a members’ profits or losses using the Daily Settlement Price to mark-to-market open positions. The collection/return of variation margin is administered by LCH.

Derivative outurns with the exception of LSEDM Norwegian contracts benefit from margin offsets and optional cross trade source netting through LCH EquityClear Service.

Buyer elections on all physical delivered contracts, excluding LSEDM Norwegian contracts, will be allowed under the EquityClear Service. Members will have the ability to choose an option or combination of options, in a participating Corporate Action giving more control over their investments, as opposed to the current default option process.

LCH will request margin on all positions and it is each member’s responsibility to meet their margin requirements

Interest Rate derivatives 5.4.

a. Initial Margin (IM) methodology

The IM methodology is based on an historic value-at-risk (HVAR) simulation and forms part of LCH’s harmonised Portfolio Approach to Interest Rate Scenarios (PAIRS) model for estimating margin across its clearing services.

http://www.lchclearnet.com/risk-collateral-management/margin-data/london-span-parameter-files


27

b. Initial Product Coverage

The products listed below are categorised into two distinct groups, namely STIR futures and Government Bond futures.

Underlying Instrument

STIRs Three month Euribor

® futures


Government Bonds

Schatz futures

Bobl futures

Bund futures

Long Gilt futures

c. Pricing methodology

Underlying LCH’s approach to pricing the various products listed above is the principle of forward pricing. Specifically, STIR futures are priced in accordance with the relevant underlying forward interest rate, while Government Bond futures are priced in accordance with the relevant underlying cheapest-to-deliver (CTD) bond i.e. as evaluated on a forward basis. Each class of product has a specific (closed-form) pricing function as detailed below.

Relevant Risk Factors:

1) Index Curves

2) Sovereign Discount Curves

3) Repo / General Collateral (GC) Curves

4) Foreign Exchange Rates

Index curves are used to estimate / project forward interest rates, which are in turn used to price the range of 3-month STIRs futures.

The sovereign discount and repo / GC curves are used to forward-price the various CTD bonds that underlie the range of Government Bond future contracts.

Give Ups 5.5.

When one side of the trade needs to be given up to another Clearing Member, it is the responsibility of the reporting member to request that both the buy and sell side of the trade go onto their own account; they will then be required to manage any give ups with their GCM directly.

Account Structure 5.6.

Members can request the following types of account from Membership through a request to [email protected]:

Client account;

House account;

Market Maker account (for Member Firms registered as Market Makers).

Membership will supply the Member Firm with a “Static Data Form” which should be used to specify account set up requirements. The member can segregate business as required. The account type is also used to indicate trading capacity. “Client” indicates agency trades. “House” and “Market Maker” indicate principal trades.

Through LCH, LSEDM currently offers Clearing Members both Omnibus Segregated Accounts (OSAs), i.e. an account held by the Clearing Member for the purposes of holding positions for one or more Clients (which may or may not be known by the Clearing House) and Individual Segregated Accounts (ISAs), i.e. an account held by the Clearing Member for the purposes of holding positions for a single named client.

Market Operations and Clearing 5.7.Processing Timetable

Please refer to Appendix A for a detailed description of trading and clearing phases across different products.



28

Clearing reports 5.8.

a) Equity derivatives

Members can extract reports summarising their activity on LSEDM from the clearing APIs and from clearing applications.

In addition, LSEDM clearing reports are available via an FTP site accessible with a user name and password. Contact Technical Account Management for FTP Service documentation.

b) Interest Rate derivatives

The Synαpse clearing system provides Clearing Members with a set of daily intraday and end-of-day reports and data extracts.

Clearing Reports are available to Clearing Members in PDF and CSV format within Synαpse and also can be downloaded from Member Web or SFTP

Data extracts can be downloaded from Member Web in XML format (content specification details can be found in the XML Specification Document)

Banking reports are available via Member Web

Synapse reports in XML PDF and CSV format are available on Member Web for 15 business days.

Exercise, Assignment and Settlement 5.9.

5.9.1. Equity derivatives

a) Exercise and Assignment

Currently, LSEDM offers two options styles on its equity derivatives markets with the following exercise windows:

Option style Exercise

Exercise Window / manual Exercises

Open Close

American style

Any Trading Day from the Trade Day until the Trading Day before Expiration Day

07:30 18:00

European style and American style

Expiration Day only

18:10 18:40

All times are London times

LSEDM applies automatic exercise for all in-the-money series.

Manual exercise can be performed through the member’s clearing application.

b) Physically Settled Contracts

If the Member holds a net Short Futures position, LSEDM shall make available normally prior to 22:00 London time on the day in question through the Clearing Application BCS, the report “Expired Futures Positions to be settled MD51”. This report provides details relating to the Settlement Delivery obligations for the Underlying Stock in respect of its own Account Transactions and of Transactions executed on behalf of a Client together with the Settlement Amount payable to the Member in respect thereof.

If the Member holds a net Long Futures position, LSEDM shall make available normally prior to 22:00 London time on the day in question through the Clearing Application BCS, the report “Expired Futures Positions to be settled MD51”. This report provides details relating to the receipt obligations for the Underlying Stock in respect of its own Account Transactions and of Transactions executed on behalf of a Client together with the Settlement Amount due to the Member in respect thereof.


29

Where a Member Exercises an Option and the Exercise is accepted by LSEDM, or the Member is Assigned, LSEDM shall make available normally prior to 22:00 London time on the day in question through the Clearing Application BCS the report “Options Exercise/Assigned to be settled MD01”. This report specifies the number of Underlying Stock to be delivered by or to the Member in respect of own Account Transactions and of Transactions executed on behalf of a Client together with the Settlement Amount payable to or by the Member in respect thereof.

The Member shall ensure that the information specified in the relating reports “MD51 and MD01” are accurate in all respects and notify LSEDM of any discrepancy no later than 08:00 London time on the Trading Day after the affected day of Delivery or Exercise.

5.9.2. Interest Rate derivatives

a) Cash Settled Contracts

Three month Euribor® and Sterling Futures are cash settled contracts as specified in the LSEDM contract specifications. Cash settlement is debited from or credited to the relevant Proprietary account or Client account.

b) Physically Delivered Contracts

Euro-Shatz, Euro-Bobl, Euro-Bund and Long Gilt futures contracts are physically delivered contracts, settled by physical delivery of the underlying at the Final Settlement Price, as determined according to LSEDM contract specifications.

c) Synapse - Clearing Component

At the time of expiry of a futures contract, the Synapse Clearing Component will mark the relevant instruments as ‘Tendered’, calculate the Final Variation Margin and convert any open futures into Delivery Positions.

The Clearing Component will provide the Delivery Component with the delivery positions. The positions will remain as unsettled until the bonds have been delivered in the Central Securities Depository (CSD) and LCH operations have marked the positions as settled.

Contingent Variation Margin (CVM) will be calculated by the clearing component whilst positions remain as unsettled.

d) Synapse - Delivery Management Component

The Delivery Component will co-ordinate the physical settlement of bonds. The Delivery Component will allow the Sellers to enter the necessary details to facilitate the delivery process.

This will include the entry of static data, the receipt of the delivery basket details made available by LSEDM and the nominations of bonds from the delivery basket.

The Delivery Component will perform the following functions:

Accept the Delivery Basket (the list of eligible instruments and price factors) from LSEDM from 10 days before the start of the delivery period and then on a daily basis until the end of the delivery period

Obtain Delivery positions and associated Final Settlement prices from the Clearing Component. These delivery positions will be maintained in the Delivery Component until settlement confirmation has been received

Clearing Member (sellers) must enter their seller notifications nominating specific instrument(s) from the eligible basket against the futures contract they wish to provide to fulfil their delivery obligations

Once the notifications have been authorised the Delivery System will then perform an allocation of Sellers bonds to the Buyers


30

Produce an Invoice and Account Sale and Delivery Instruction report for the Clearing Members

Pass any positions in Delivery to the Risk Management Service for calculation of Initial Margin

Provide delivery instructions to the appropriate CSD in order to initiate settlement

LCH operations will monitor the settlement confirmations from the CSD and update the associated delivery positions as settled within Synapse.

Note there will not be any capability for a Clearing Member to nominate a transferee/transferor for the Delivery process.


31

6. Risk Controls

Order book 6.1.

6.1.1. Price controls

Circuit Breakers will activate and trigger suspension of trading when a trade occurs at a price level deemed to be an unacceptably large deviation away from static or dynamic control prices defined by LSEDM.

Product Duration of suspension of trading following Circuit

Breakers

Equity derivatives 60 seconds

Interest Rate derivatives 5 seconds

LSEDM can set separate Circuit Breakers against the static control price with respect to both orders and trades. In particular market conditions, LSEDM may, with reference to markets, categories of financial instruments or individual instrument modify the maximum price variation limits, the static price, the dynamic price and other trading conditions.

Definitions of control prices are as follows:

Static control price – the previous day closing price, as determined by the London Stock Exchange Derivatives Market (or CC&G, where applicable);

Dynamic control price – the last traded price in the current session.

Levels set by LSEDM are detailed in Appendix D.

For Stop Loss and If Touched orders, the incoming order price cannot be outside the price control thresholds detailed in Appendix D. Additionally if, when triggered, the price on such an order violates the control parameters, the incoming order is deleted and the Circuit Breaker suspension is triggered. In the event that the Circuit Breaker will

continue to persist due to a member’s order(s) that is outside the static or dynamic thresholds and LSEDM has taken reasonable action to contact the member in relation to that order and the member has not responded, LSEDM reserves the right to delete the order to resume continuous trading.

6.1.2. Too Deep Trading Safeguard (for Norwegian Derivatives only)

The Too Deep trading safeguard validates incoming limit orders by comparing the limit price with the current order bids and offers on the order book.

Limit buy orders are validated against the best offer price, and are rejected if the price exceeds the best offer price by more than the too deep limit. Likewise, limit sell orders are validated against the best bid price, and are rejected if if the price is lower than the best bid price by more than the Too Deep Limit.

The Too Deep Limit states the number of ticks a limit order may deviate from the bid (for sell orders) or offer price (for buy orders) without being rejected.

Too Deep Limits can be found in Appendix D.

6.1.3. Self Execution Prevention (SEP)

LSEDM trading platform provides Self-Execution Prevention (“SEP”), with the purpose for market participants to avoid execution when an order crosses an opposite-side order sent by the same trading Firm on the orderbook (i.e. “self matching”).

SEP on SOLA is user-configurable, allowing for each market participant to specify which Trader IDs of its Member Firm will or will not be able to interact, and determine which order (incoming or resting) takes precedence. SEP applies during continuous trading for Limit, Market, Top, Stop (loss) and If-Touched orders.

Basic functionality:


32

Market participants can define one or more Self-Execution Prevention Groups (“SEP Group”) for their Trader IDs. Members can set up their SEP Groups by contacting their Technical Account Manager at [email protected]:

A SEP Group will contain one or more TraderIDs from a particular Member Firm. A SEP Group cannot include TraderIDs from multiple Member Firms. A TraderID will be allowed to be associated only to one SEP Group.

o Orders submitted from TraderIDs within the same SEP Group will not be allowed to interact with each other;

o Orders submitted from TraderIDs in different SEP Group will be allowed to interact with each other.

SEP will take effect upon aggression of the order (before execution) and not on order entry or replenishment.

The diagram above explains how the interaction between TraderIDs / SEP Groups works on SOLA.

“SEP Rules” regulate the interaction of orders from a Member Firm and are defined at the TraderID level. Different rules can be applied to TraderIDs included in the same SEP Group. The

SEP rule of the incoming order (i.e. the aggressive order) will regulate the interaction between two orders which are part of the same SEP Group.

SEP behaviour is managed differently in relation to the matching algo in use by the product:

for products based on Price-Visibility-Time priority, assessment of SEP rules is done



33

before the potential execution of every individual trade triggered by the incoming order;

for products based on Progressive Pro-rata matching algo, SEP is evaluated at each relevant price level, before starting the allocation process described in Appendix B.

The following SEP Rules will be available for each TraderID:

Cancel Incoming Order (CIO): leaves the resting order (all resting orders at the relevant price level - and belonging to the same SEP group - in case of products based on Pro-Rata matching algo) while expiring the incoming order;

Cancel Resting Order (CRO - configurable only for products based on Price-Visibility-Time priority): expires the resting order while allowing the incoming order to aggress (and rest in the book if it is not matched);

Cancel Both Orders (CBO - configurable only for products based on Price-Visibility-Time priority): expires both the resting order and the aggressing order;

Reduce and Cancel (RC - configurable only on products based on Price-Visibility-Time

priority): cancels both orders if they are of the same size. For those not of the same size, the smallest order will be cancelled and the larger order will be reduced by the size of the smaller order before executing/resting. Both orders will also be cancelled if the resting order is marked with any SEP (other than RC) and the incoming order is smaller than the resting order.

The table above explains the expected behaviour of SOLA when orders/quotes from TraderIDs from the same SEP Group interact.

Exceptions to SEP Rules:

If a self-execution is identified involving a quote (as a resting or aggressive order), the SEP Rule attached to the incoming TraderID will be ignored and the following rules will apply: o In case the opposite side is an order (i.e. it

is not a quote), the quote will survive while the order (incoming or resting) will be cancelled;

o In case the opposite side is a quote (e.g. two quotes submitted by two different TraderIDs of the same market participant), no SEP rules will be applied i.e. the trade will be executed.

Strategies: SEP will only apply for orders with potential executions in the “Strategy v Strategy” scenario, i.e. if a strategy instrument could execute against another (resting) strategy instrument, SEP will prevent this execution. SEP will not apply in the Strategy vs. Legs case, i.e. when a strategy instrument could execute against orders on the Order book, the trade will be executed.

Minimum quantity orders: SEP will not apply to execute minimum quantity orders, including icebergs, Fill Or Kill (FOK) and Fill And Kill (FAK) orders.

“Internal” cross orders: SEP will not apply to cross orders with the same counterparty on both sides.

6.1.4. Order Quantity Controls

Orders are reviewed by LSEDM Market Supervision for purposes of market quality. Product specific settings are in detailed in Appendix D. The futures contracts value ranges are available in Appendix E.

Price Controls on Block Trades 6.2.

a) Block trades trade reported using SOLA available functionalities

Block trades on Standard series electronically submitted to LSEDM will be subject to the following system controls or controls by Market Supervision:

Minimum and maximum quantity controls;

Price controls to allow trades to be reported either within the order book bid and ask or within the allowable % from the order book bid and ask.

Trades may be reported electronically as Block, provided that all legs of the trade are within bid/ask (or the allowable % from bid/ask) for each product, if at least one of the following conditions is met:

o For trades or strategies including one or more legs in the same product the sum of all legs must meet the minimum quantity for Block Trades within bid/ask (or minimum quantity for Block Trades outside spread) of the listed product being traded.

o For trades including one or more legs in different products (excluding trades across different instrument types, i.e. options and futures) the sum of all legs must meet the largets of the minimum quantity for Block Trades within bid/ask (or minimum quantity for Block Trades outside spread) of the listed products being traded.

o For trades including one or more legs in products across different instrument types (i.e. options and futures), the sum of the option legs must meet the largest of the minimum quantity for Block Trades within bid/ask (or minimum quantity for Block Trades outside spread) of the listed options being traded.

Trades reported as Block Trades that do not

meet either of the conditions outlined above, will not be accepted by the trading system or cancelled by Market Supervsion.

Product specific settings are detailed in the Appendix D.

Block trades on Tailor-made (Flex) series electronically submitted will be subject to a post-trade theoretical price validation check by LSEDM Market Supervision. The Exchange may unilaterally cancel any block trades that fail to meet its controls.

b) Block Trades trade reported through a manual process (where applicable)

Block trades sent to LSEDM Market Supervision for Trade Reporting using pre-defined templates are subject to price controls by LSEDM Market Supervision and must


35

comply with the same conditions outlined for trades that are submitted electronically;

for Tailor-made (Flex) series, block trades will be subject to a theoretical price validation check by LSEDM Market Supervision.

Bulk Quoting Protection 6.3.

Bulk quoting protection is a functionality provided by LSEDM that will result in an automatic cancellation of all quotes in a particular instrument class under certain conditions.

The feature protects Bulk Quote users against any “excessive” trades due to the following:

Technical problems at participant’s end preventing normal market updates

Quoting errors at participant’s end due to erroneous underlying price information

Unintentionally being “swept” by another participant

6.3.1. Bulk Quoting Protection Types

Bulk quoting protections apply to each trader ID for an underlying instrument group. Users may opt for one of two types of bulk quoting protection:

Standard protection: If protection is triggered on an instrument class, quoting will be restarted

and counters (detailed below) reset the next time a bulk quote message is sent to any instrument in the class.

Advanced protection: If protection is triggered on an instrument class, any subsequent quote update is rejected and quoting can only be resumed after a new “Protection subscription” (RP) message is sent.

Once protection is triggered, the London Stock Exchange Derivatives Market will automatically cancel all quotes posted by the trader on all instruments in the class and send a “Notice of cancellation of all quotes” (NP) message.

6.3.2. Protection counters

Bulk quoting protection is active on all quotes sent using the Bulk Quote message functionality.

LSEDM provides five protection counters which can be set by Firms using bulk quotes in a specific instrument class. Any number of counters can be activated simultaneously. Traders must define a “Time Interval”. The protection counters are reset in the event that the time elapsed between any two trades is longer than the user defined “Time Interval”.

Protection counters are listed and described in the table above.


36

6.3.3. Default protection and ranges

LSEDM provides default thresholds for the protection counters within the Trading System (see Appendix H). LSEDM sets the default to ensure adequate protection for bulk quote users. Bulk quote users may define their own customised thresholds. When defining their thresholds, users

must adhere to the minimum and maximum configuration ranges in the tables in Appendix H. If a value outside the relevant minimum or maximum is selected, LSEDM will reject the message and users will be unable to set up their customised protection thresholds.The protection must be activated before the start of each trading day by sending an “RP message” to select the type of protection (Standard or Advanced). For each trader ID, bulk quote users need to send a “bulk quote” message (BD) to begin their quoting activity with the user defined thresholds (including the Time Interval, Maximum Volume and Value limits, and Maximum Delta Volume and Value limits).

If the values of the thresholds are not user defined, then the LSEDM default thresholds are selected, as in Appendix H. For further information on the Bulk Quoting Protection functionality, please refer to the Bulk Quoting Protection Description document on the LSEDM Document Library.

Pre-Trade Validation Service (PTVS) 6.4.

PTVS provides a tool for:

General Clearing Members (GCMs) to manage the cleared risk exposure generated by the trading activity of their NCPs;

LSE Members offering Direct Market Access (DMA) to control the risk related to the trading activity of their DMA clients;

LSE Members to monitor the risk associated to their own trading activity.

PTVS allows the Risk Manager (controlling entity) to set pre-trade controls for a specified Managed Entity (i.e. a single TraderID or a group of Trader IDs associated with a Firm) and at different levels, in particular:

Counter type Counter change condition

(applies to all trades in any instrument of the class) Trigger for bulk quoting protection

Trade count (of Min Lot Size)

Increases by 1 with each execution of a trade of at least N lots (where N is a user defined number). Max number of trades = Count (Trade where volume ≥ Minimum Trade Volume)

In advance of setting up pre-trade validation controls, the Risk Manager should inform the Managed Entity that these will be implemented; if in doubt, the Managed Entity should check with its Risk Manager whether pre-trade validation controls are applied to its orders.

The following limits can be configured by the Risk Manager via both SOLA native APIs (SAIL) and a dedicated GUI:

Max Order Quantity limit for orders and quotes;

Max Order Quantity limit for cross/bundled/third party orders (available for Equity derivatives only);

Position limit6 on executed trades (net

long/short position) during the day, expressed in quantity terms: o the trade triggering the limit’s breach is

executed o the breach of the net long threshold

triggers the cancellation of all buy orders and all quotes (and vice versa for the net short threshold);

Exposure limit6 on open orders (excluding

quotes) plus executed trades (net long/short position) during the day, expressed in quantity terms: o the incoming order that would breach the

net long threshold triggers cancellation of

6 For the purpose of calculating Position and Exposure limits for

Interest Rate derivatives, the following are out of scope: a) cross/bundled/third party orders and trades; b) iceberg orders and trades (since not available for these products).

all buy orders and all quotes (and vice versa for the net short threshold);

Kill Switch functionality, allowing to cancel all orders (cross orders included) and quotes for a TraderID and to disable the TraderID / Firm;

Access to the Market Maker Protection to control quoting activity of Managed Entity. Since the MMQP is available to both Market Makers and their Risk Managers, in case two sets of limits are applied to the same Managed Entity, the most restrictive configurations will apply.

Based on configurations defined by the controlling entity, SOLA will perform real-time checks before allowing each order and quote to enter the Trading System; configured limits can be updated real-time with immediate effectiveness.

SOLA will disseminate messages related to the “usage” of the predefined Position and Exposure limits (“Risk Limits Usage Notice”) via both SOLA APIs and GUI:

anytime a defined limit approaches the threshold, an alert is disseminated according to a 10% interval

alerts are disseminated when the available thresholds “used” are at 50%, 60%, 70% etc. of its total.

These messages are available for SAIL protocol, while FIX protocol only disseminates error codes.

For further details on PTVS, please refer to the “LSEDM Guide to Pre-Trade Validation Service”.

7. Tariff Models

LSEDM operates several products with specific pricing models. Tariff schedules are available on the LSEDM Document Library.

The different tariff models currently in use on LSEDM are detailed below.

Fee per lot

Products using this system simply apply one universal fee to each side of the trade based on the number of contracts traded, Per-Trade Charging

Percentage of Futures value

Some products are charged based on a “percentage of future value” system, for example IOB Dividend Futures.

Future Value = (future price traded) x (number of contracts) x (multiplier)

Percentage of premium value

Some products are charged based on a “percentage of premium value” system, for example IOB DR Options

Premium Value = (premium) x (number of contracts) x (multiplier)

STIRs Progressive pro-rata matching algorithm, with Best Price Setter

Progressive pro-rata allocation apportions volume to matching resting orders according to their relative sizes adjusted by a time weighting factor which increases the allocation of volume to older orders in the orderbookIn particular, the current product configuration is set to:

Three month Sterling futures:

Best Price Setter: Enabled - Min = 50; Max = 500 - Allocation = 100%

First pass allocation: - Collar = 1; Cap = 9999; Split = 100% - Time Weight = 3

Residual Policy: - Re-sort = None - Method: FIFO

Three month Euribor® futures:

Best Price Setter: Enabled - Min = 50; Max = 500 - Allocation = 100%

First pass allocation: - Collar = 1; Cap = 9999; Split = 100% - Time Weight = 1

Residual Policy: - Re-sort = None - Method: FIFO

LTIRs Price-visibility-time priority N/A

Pro-rata matching

The Pro-rata matching algorithm is run in three steps:

i) (where applicable) a specified quantity of the incoming order is allocated to the “Best Price Setter” resting order, on the basis of the parameters described under “Best Price Setter” above;


44

ii) the remaining quantity of the incoming order is allocated to resting orders on a pro-rata basis - orders at best price levels are allocated first; in case total quantity at one price level is more than the available remaining quantity of the incoming order, a pro-rata allocation is applied among all the available resting orders at that price level - with the pro-rata allocation policy determined on the basis of the parameters described under “First pass allocation” above;

iii) any residual quantity of the incoming order (if any) is allocated on the basis of the “Residual policy” configured and its related parameters.

Best Price Setter (BPS)

The “Best Price Setter” status is assigned to an incoming order which determines new best price level (in bid or offer) of the order book. The quantity of an incoming order allocated to the Best Price Setter is determined on the basis of the following parameters:

- Min = represents the minimum quantity that can be allocated to a BPS order. In case this quantity cannot be satisfied, BPS status is not assigned to the order and all the residual quantity is sent to the First Pass Allocation;

- Max = represents an absolute maximum quantity (in units) that can be allocated to a BPS order;

- Allocation = represents the maximum quantity (in % of the incoming order quantity) that can be considered for allocation to a BPS order.

First pass allocation

In the First Pass allocation, the policy to allocate residual quantity can be “FIFO” or “Pro-rata”:

- under “FIFO”, resting orders are fully filled based on their time priority, until no resting quantity reremains. In this case, the “Residual policy” step is not necessary;

- under the “First Pass pro-rata” allocation policy the quantity to be allocated is determined on the basis of the following parameters:

o Collar = represents the minimum incoming quantity that must be available to allocate via the First pass. In case this quantity cannot be satisfied, all the residual quantity will follow FIFO allocation;

o Cap = represents the maximum quantity (in units) that can be allocated during the First Pass;

o Split = represents the maximum quantity (in % of the tradable quantity) that can be allocated during the First Pass;

o Time weight = is the parameter governing a time-based component in the allocation policy during the First pass.

- when set to 0, no weight is attributed to the time-priority component;

- when given a numerical value (1.5), the higher the parameter, the greater the weighting for allocation given to resting orders that have a higher time-priority (“Progressive pro-rata”);

- If set to “A” this will implement the “Age pro-rata” allocation whereby allocation to each applicable resting order is determined by both the unallocated quantity of the incoming order and the age of the order (length of time present in the order book) in comparison with the oldest eligible order that is still present in the book at that price level.


45

Residual policy

In the Residual policy pass, the policy to allocate any residual quantity can be configured to be “FIFO” or “Residual Pro-rata”.

- under “FIFO”, resting orders are fully filled based on their time priority, until no resting quantity reremains;

- under the “Residual pro-rata”, resting orders are filled sequentially, in proportion to their residual unexecuted quantity.

Note that allocation of any residual quantity under the “Residual pro-rata” is determined on the basis of the “Re-sort” parameter. At the end of “First pass allocation”, resting orders can be re-sorted before the allocation of any residual quantity. It is possible to:

- maintain the original time priority (no re-sort);

- re-sort by size (orders with biggest unexecuted quantity after the first pass allocation are ranked first), or;

- re-sort by allocation (orders with lower allocated quantity after the first pass allocation are ranked first).

yp

e

Limit order Enters Order book at specified price and will execute at that level or better. Residual is retained on order-book (unless designated as an immediate order) until withdrawn or traded.

Market order Executes at best available price until all volume on opposite side has been traded. Residual is converted to a limit order at last price that original order was executed.

Top order Executes at best available price against any single contra order. Residual is converted to a limit order at price just traded.

Stop (loss) order

Order enters book to prevent further loss once either last price or bid/ask (as selected) reaches a stated trigger price. Entering order can be set as limit order by entering a specific order price. Alternatively, it can be set as a market order by leaving order price field blank. Residual is retained on book.

If-Touched order

Order enters book seeking to capitalise once either the Last price or Bid or Ask (as selected) reaches a stated trigger price. Entering order can be set as limit order by entering a specific order price. Alternatively, it can be set as a market order by leaving the order price field blank. Residual is retained on order-book.

Minimum quantity order

Tries to execute at the specified price for at least the stated ‘Additional Quantity’ (AQ). If the AQ cannot be immediately filled, the order is rejected. If the AQ is filled, the residual is retained on the Order book and can trade without further quantity constraints.

Iceberg/disclosed quantity order

Enters book as Limit order for only the ‘Additional Quantity’ (AQ) visible, and any balance is held “in reserve”. The visible quantity is assigned time-priority at the point of insertion in relation to other displayed orders, whilst the reserve quantity is assigned time priority in respect of other non-displayed orders. When this disclosed/ AQ amount has been traded, the system refreshes the visible quantity from the reserve quantity.

Block Trades 11.2.

Order type Description Effect market data Matching requirements

Cross (committed)

Matching facility to support reporting of BNT between different members for the purpose of trade publication and clearing. Trades must specify the intended counterparty and do not interact with the anonymous orderbook. Trades stay in the cross book until the end of the day unless matched or deleted.

Trades must meet certain quantity and price threshold determined by LSEDM on a product specific basis. Trades contribute to the Market Data Feed with quantity and price updates.

Both sides must enter a cross order with opposing buy and sell sides, same price, same quantity and the correct counterparty or the trades will not match.

Cross orders not matched by the end of the trading session are automatically deleted.

Cross (internal) Trade is pre-arranged by one member acting on behalf of each side and reported to LSEDM. Trades do not interact with the anonymous orderbook.

Matching not required as trade details are entered by one participant only.

Bundled

Members are allowed to group several bilaterally negotiated trades on same/different instruments within an unique order, offering certainty of simultaneous execution, or no execution at all. Each leg of the Bundled Order must specify the intended counterparty and do not interact with the orderbook. Trades stay in the cross book until the end of the day unless matched or deleted.

Each leg must be approved by the opposing counterparty (same price, same quantity), otherwise the trades will not matched. Once all legs are approved, trades in the Bundled Order are confirmed and sent to clearing. Legs of the Bundled Orders not matched by the end of the trading session are automatically deleted.

Third Party

Members registed as Reporting Brokers can arrange a trade between two or more Members and use the Third Party Order to initiate the execution process for a cross order. Each leg of the Third Party Order must specify the intended counterparties and do not interact with the orderbook. Trades stay in the committed book until the end of the day unless matched or deleted.

Each leg of the trade must be approved by the relevant counterparties (same price, same quantity), otherwise the trades will not matched. Once all legs are approved, trades in the Third Party Order are confirmed and sent to clearing. Legs of the Third Party Orders not matched by the end of the trading session are automatically deleted.
