Place an order into the matching engine queue, conditional on validation. A successful response indicates that the order was placed in the queue, but does not guarantee that it will be filled or placed on the order book. To reliably ensure that an order has been executed, consume messages from the matching tape to reconstruct the order book and other stateful structures.
Note: If an order placed wash trades against an order from the same user, both orders will wash fill each other and effectively be cancelled.
