Hello D-T-S,
Square involves only the premium. You simply keep the diff. between buy and sell prices.

You are right about point 2. u don't need margin to buy options.
Thanks Rajsingh for your reply.
From what you said, I make out that - settlement price is weighted average price in Capital market in last half an hour of trading.
So, even if you exercise/square off your option at any time during trading hours, it gets executed only after the settlement price is derived at the end of the trading day. Is that right?
My second query:
1. In buy option, on squaring off, the profit will be = (Difference in premium)*Lot size* No. of lots
CMP is current market price
2. In Buy option, on exercising the option, the profit will be = (CMP - Strike price)*Lot size* No. of lots.
Any idea - which one of the two - exercising or squaring is more profitable?
Have I got my mathematics right?
