Dear sir,
Let me emphasise STT in exercised options is 12500/crore of contract value is applicable.
For example : Bank Nifty Strike Price 25000 call or put options.
Calculation of STT in case of exercised option by exchange will be =
Contract Value {(Strike Price + Premium) X Quantity} X .125/100
So if Bank Nifty strike price is 25000, STT will be 25000X40 = 1000000 X .125/100 = 1250/- for a single lot.
Now we traders have a tendency to buy options in huge lots just say hundreds or thousands and which resulting them huge losses by virtue of STT.
To avoid such losses we caution traders to square off ITM options on expiry day, however clients who do not square off positions by 3.15 pm and who are running short in their ledger balance we square off their position end of the day.
I want to know, about your rms policy of squaring off (forced squaring off) of option trades (buy side, fully paid), that are in ITM or ATM, on expiry day.
