This setting changes how Tamarac Trading handles negative cash in the account. If you select Yes, Tamarac Trading will allow the account to hold a negative cash balance. If you select No, Tamarac Trading will not allow the account to hold a negative cash balance, and will recommend trades to raise cash during a rebalance.

If you upload a negative cash position and Automatically Maintain Margin Balance with Additional Cash is set to Yes, Tamarac Trading adds an Additional Cash amount to bring the account's initial cash balance to $0.

Accounts set to Yes typically should not have a cash reserve.
