Quick Surveys● How many of you use R ? ● How many of you did have some REAL trading experience in financial market

? ● What kind of signals & strategies did you use in trading ? (your intuition is also

one kind of useful signal too)

● Did anyone use MultiChart ? AmiBroker ? Interactive Broker APIs ?● Did anyone use quantmod ? blotter ? quantstrat ?

Basic Concepts of making quantitative trading strategy

What is the only wayto make money from market ?

The Only Way is ... ● Buy Low and Sell High● Trends up: Buy first, then sell● Trends down: Sell first, then buy

Arbitrage or Anti-arbitrageE = pW - (1-p)L - T > 0

Arbitrage or Anti-arbitrageAssum T = 0, WLR = W/L

p > 1 / (1+WLR)

Blindness of MLBlindness from PCA

Blindness from Vector Quantization

The two keysHelp you apply machine learning

in the real world

Can Learn ONLYThrough Real

Practice

Can Learn fromSchool or Practice

Modeling Procedures:● Choose a Real Problem● Collecting Related Data● Choose a method convert Data to Vectors (or Tensors)● Decompose Real Problem into several ML or Math Problems● Solve each ML or Math Problem individually ● Combine the Solutions of all ML or Math Problems● Check is that truly solve the Real Problem ?

(ref: Moving Forward through the Darkness)

Machine could NOT Learn by itself.

It just like a child.It learn by training data !

sometimes would learn badly!
