Abstract

See full text

New data messages for updating a database can indicate a latency tolerance. The latency tolerance can constrain new data records based on such new data messages to also indicate the latency tolerance. Latency-tolerant data records can be constrained to remain in the working database for a minimum duration. Data records present in the working database can be prioritized according to prioritization criteria that increases priority of data records indicating latency tolerance. Matching incoming data messages with the data records present in the working database can be based on such prioritization. A matched data record can be updated or deleted upon successful match with an incoming data message. The latency tolerance can be applied to trading systems for financial instruments or interests as a long-life order that rests in an order book without being able to be cancelled or updated for the minimum duration in exchange for priority during order matching.
