Deal matching in an anonymous trading system
View Patent ↗An anonymous trading system comprises an interconnected network of broking nodes arranged in cliques which receive buy and sell orders from trader terminals via connected trading engines and which match persistent orders, executed deals and distribute price information to trader terminals. Where two orders are matched, a proposed deal message is sent by the matching broker. If another broker has processed an event which makes the matched quote unavailable the match fails and rematch may occur. Rematch may be attempted by an intermediate broker provided it owns one side of the match, or it received both sides of the match from brokers in different cliques. The intermediate broker attempts to match with the next available quote in the queue.
1. A node in a computer trading system, the node including computer executable software for performing the steps of:
receiving notifications regarding at least a first quote from a first node and a second quote from a second node;
storing the first quote and the second quote in a store of orders;
receiving a notification regarding a hit from a third node for the first quote;
receiving a notification that the first quote is no longer available and that the hit did not match with the first quote because the first quote is no longer available; and
matching the hit with the second quote in the store of orders.
