F&O Margin Debit/Credit Process

Will any Margin get debited if I have taken the positions by blocking shares in my Demat Account?

Yes, the margin will get debited in any of the following scenarios : a) In case the total margin required on your total open positions is met by the blocked shares alone, in such case no funds would be debited as margin from your account even if there are idle funds lying in your linked bank account. b) In case the total margin required on your total open positions is partially met by the blocked shares, in such case the balance required margin amount at end of day shall get debited from your linked bank account. c) In case there are no blocked shares in your account, then the entire required margin amount at end of day shall get debited from your linked bank account.
