Abstract: Market data is monitored for purposes of canceling orders for financial articles of trade. Real-time data is collected from multiple liquidity destinations trading at least one financial article of trade. The real-time data comprises disparate data corresponding to associated liquidity destinations. The collected real-time data is normalized into a standardized form. A condition is defined of a trading market that includes one or both of submitted and executed transactions of financial articles of trade over the multiple liquidity destinations. The condition is associated with an entity. Through monitoring of the normalized real-time data, an event is identified in the trading market that matches the condition. Upon identification of the condition, at least one communication session between the entity and a corresponding liquidity destination is terminated causing a process at the corresponding liquidity destination to cancel pending or outstanding orders for financial articles of trades from the entity.
