Futures Indian Market Perspectiveh h h h ff d NSE & BSE are the exchanges which offers trading in
Futures. Contracts are available for different tenures(expiry)( p y) Typically contracts are available for 1,2 or 3 months Last working Thursday is the date of expiry for that month.
If Thursday is holiday then last Wednesday is consideredIf Thursday is holiday ,then last Wednesday is considered. Buyers and sellers will not take or give delivery of the
underlying.fi & l d i h Profit & Loss are settled in cash.
Since there is no delivery of the underlying ,we couldtrade in broad indices like NIFTY.NIFTY is most traded bothfor Futures & Options
One can start trade in Futures by paying small % ofcontract value known as margin.co t act a ue o as a g
Contract size and margin are set by exchange.Chapter 1 /Harsh/2013 14

$2000 is cost of option .Thus Option buying is 10 times more profitable.
