Systems, methods, apparatus, computer program code and means for generating quality data associated with an option limit order are provided. In some embodiments, an option limit order is received, the option limit order including information identifying a customer, information identifying a desired option, and information that indicates a limit price for said option limit order. A substantially real time feed of option market date is received and the option market data is used in real time to identify at least one of a trade-through and a trade-at transaction relevant to the option limit order. Alerts may be generated based on the identified trade-through or trade-at transaction. Trade-at or trade-through data may be tabulated and analyzed to evaluate option limit order trading activity. Analysis to generate trade-at or trade-through data may be performed on a batch processing basis relying entirely or in part on data received in real time or on a batch basis.
