for the 24th june stocks expiry ; do u allow to trade in options NRML until what date ?
So can a option seller save the brokerage of 20rs/order (considering I have 10 orders so 10*20=200rs of brokerage saved ) in case he doesn’t square up the position and let it expire worthless which is OTM?
Yes, 20 rupees in brokerage per order. Also if you are option seller you can let them expire if they are OTM
