but what i understand:
1. a brokerage of Rs. 1 on an options contract, man you must be kidding.
2. the brokerage look ok only if you pay .1% or more as your brokerage (for 5 lots of nifty), but as vince said no one can help unless you give details.
3. the most likely probability, you got screwed by your RM. with 90 paisa as premium one should not trade at all. they play dirty tricks to meet their target.
