System and method for a risk check

Various systems and methods are described herein for a risk check. The risk check bases a decision to allow a trading strategy to proceed on whether the order quantity for each leg of the trading strategy satisfies a certain condition. Particularly, when a trading strategy is initiated, the quantity for each of the orders to be submitted on behalf of the trading strategy, including the quantity of the initial order and any subsequent orders, is then compared to a corresponding risk value. If the order quantity for each of the orders is less than the corresponding risk value, then the trading strategy can proceed and the initial order can be sent on to the exchange. However, if the order quantity for any of the orders exceeds the risk value, then the initial order is not sent to the electronic exchange. Additionally, as described herein, quantity associated with the trading strategy is held or reserved for execution of the trading strategy regardless of the activity taken by the trader since the trading strategy was initiated. The reserved quantity can be drawn from the trading strategy until the quantity is depleted, the trading strategy has ended, or both, for example.
