I want to invest all my money in trading account in some Balanced Mutual Fund. Can a collateral on that mutual fund can be treated as margin on Options position?(Not for intraday) Presently I am with SBICAP. They insist 100% cash as margin amount on option positions. They say it is as per new rule specified by SEBI. i came to know some brokers allow this collateral as margin. Any way-out?
