Order Execution
An Order Execution is sent for each fill on an order.
Rather than returning a monetary value indicating the rebate or charge for an execution, the FeeCode is an indication of a fee classification corresponding to an item on the venue's fee schedule.
For executions involving Spread orders, if both sides of a complex/spread trade are on the same order entry session, Cboe does not guarantee that the leg executions will not be interleaved between sides.
