Buy 2 lots of bank nifty (otm) option strike price 36000. @ 62
spot price 35710
after some time bank nifty spot traded at 36220
now (otm) option become (itm) @ 230
on expiry day.
this trade cost 62 x 50 = 3100 only. is enough margin or we need more because otm converts into itm.
what happens if we close before market close or we didn’t?
