Hello all., 

    I have two question.. 

1) How much it cost for pledge and unpledge..

2) If I want to sell an atm option I approximately need 1.65L.. So how much minimum fund I need to have in my account and how much pledged money I can use.. Is there any percentage for this  

And clarify the percentage for cash and collateral  for intraday option selling also.. So it will be useful to me
