Order Executed at Price/Size

Order Execution at Price/Size messages are sent when a complex order on the Cboe complex book is executed in whole or in part at a different price than the limit price on the original Add Order message or the limit order price in the latest Modify Order message referencing the Order Id. If the Remaining Quantity field contains a 0 the complex order should be completely removed from the complex book.

Order Execution at Price/Size messages may also be sent in the event the existing size for Order Id is not equal to Executed Quantity + Remaining Quantity. In this case the complex order should be prioritized the same as a new complex order.
