Today Bank Nifty close that 25126 where I could see 19th April Bank Nifty 25200 put cost around 57 rupees and 19th April 25100 call cost around 20 rupees. So if I buy why this put and call at the above mentioned price what would be my profit as the option expired today?
STT is 32 points per leg …
25100 CE settled at 26 which is less than STT , so wont be exercised … net 0
25200 PE settled at 74 … credit 74 - 32 stt = 42pts
your net loss is 35 pts 
Thanks bro
