How can I use the Collateral margins and is there any limitations to it?

Collateral margins can be used to trade futures, sell options, and also to trade in intraday equity. These margins can be used for the available margin shortfall in the trading account and will be reported to the exchange as the upfront margin collection for all these trades.

Note: 50:50 Cash ratio applies for both Cash collateral and Non-Cash collateral, also Cash-equivalent securities will no longer be considered to meet the 50:50 requirement for Non-Cash collateral.
