When processing futures trades in StrataSearch, the margin amount identifies the amount of cash required to purchase a single contract. The margin is configured in the Futures Product Setup. The FuturesMargin column in the Detailed Analysis identifies how much cash has been removed from the CashBalance and AvailCashBalance columns to cover the futures margin requirements of held futures positions.
Futures Margin amounts can earn interest. See the Credit Interest on Margin setting for futures on the Trade Amounts tab of the Trade Settings.
