Want to know how this particular option will get settled. If nifty is at 23000 at 15:27 , and bought PE which is trading at say 5 , if now suddenly a 50 point fall comes and it closes at 22950 , will i not get 50*25 at settlement? It wasn’t trading above 5 in the market but nifty closed 50 points lower
After 3.10 - 3:15 pm, you will generally see options pricing in the possible expiry price range based on 30 minute average price and adjust itself accordingly.
So, the scenario that you mentioned about the last 3 minute is very unlikely and almost improbable as premium would already be adjusted to 50 at 3.27 pm assuming the closing price at 3.30 pm
STT is charged on exercised contracts at the rate of 0.125% of intrinsic value (how much in-the-money the option is), i.e. intrinsic value * quantity and not on the total contract value.
Brokerage will be charged on both sides, i.e. when the options are bought and when they are settled on the expiry day.
Just like other F&O trades (T+1 day). You can check the amount tomorrow morning.
