摘要
Electronic messages regarding a current order status of an order book of an electronic exchange system are transmitted to users including information concerning identities of parties having placed orders stored in the order book. The current order status is associated with a queue of orders stored in the order book. Each stored order has associated properties and an associated queue number. A higher queue number indicates a lower trading priority than a lower queue number. An electronic order message is received to trade selecting an order stored in the order book having a queue number of two or higher than over a lower queue number order stored in the order book. Both the selected order and the lower queue number order have properties matching both the selected order and the lower queue number order. The received message is identified as including information that selects the order stored in the order book having a queue number of two or higher. The received message is matched with the selected order stored in the order book having a queue number of two or higher. The lower queue number order remains stored in the order book after the matching.
