ITM option at the expiry


Can some one please clarify, if the difference between in the money contract and spot price at the closing difference should tally?
For instance if I hold a contracts of nifty 10750 PE and nifty expired today at 10737.55 then the difference between nifty spot price and put option strike price should tally?
Does that mean I should get 12.45 point profit.


From Sep 1st that will be effective.


yes but right now u will pay about 14 point in nifty(10750x.125%=13.4) as STT if u let it expiry. if your profit is such low, exit it before expiry. STT is way lower if exited before expiry.
