  • Storage of order books with persistent data structures
    Patent number: 11797480
    Abstract: An electronic message is read, and a delta is generated based on a comparison of the electronic message to an existing order book. A new order book is generated based on the delta. An event is generated based on the existing order book, the delta, and the new order book. A sequence of events, including the event, is accumulated in a queryable persistent data structure over a time span. The queryable persistent data structure thus efficiently stores representations of order books.
