Peak Margin

Why is my Peak Margin amount showing positive value instead of zero even though there are zero trades placed during the day ?

In case you have carried forward open marginable position from previous trade date then the peak margin column will display the total margin amount utilized to maintain those positions even though there are no trades placed on trade date. However, the actual peak margin for that trade date will be displayed in Peak Margin to be debited column which will be updated only when any fresh trade occurs for the day.
