}Get FCM Subtrader Event Contract Daily Cap
Returns the event-contract daily premium cap configured for an FCM member’s subtrader, together with its live utilization. Executed utilization is the net premium deployed by fills today (sells and settlements credit back); resting and pending utilization reserve open and in-flight orders at their full worst-case cost plus fees. Executed utilization resets at midnight New York time on the returned cap date; resting and pending reservations persist for as long as their orders remain open, including across the reset. Returns 404 when the subtrader has no cap configured — in that state every order placed through the subtrader’s bound API keys is rejected.
