Abstract

Claims (59)

1. A system, comprising:

a processor; and

a memory, wherein:

the processor and memory are configured to implement a first matching engine, a first orderbook, a second matching engine, and a second order book;

the first matching engine is configured to:

receive an order entry message from a first device;

create a modified order entry message by adding status data to the order entry message, wherein the status data relates to an operating state of the first matching engine; and

forward the modified order entry message, including the status data, to the second matching engine;

the second matching engine is configured to:

receive the modified order entry message forwarded by the first matching engine;

process the modified order entry message by attempting to match order data in the modified order entry message using the second orderbook;

generate confirmation data associated with the status data contained in the modified order entry message; and

forward the confirmation data to the first matching engine; and

the first matching engine is further configured to:

receive the confirmation data from the second matching engine.

2. The system of claim 1 , wherein the first matching engine is further configured to transmit broadcast data based on the received confirmation data.

3. The system of claim 1 , wherein the confirmation data is generated by comparing an operating state of the second matching engine to the operating state of the first matching engine based on the status data contained in the modified order entry message.

4. The system of claim 1 , wherein

the status data includes a sequence number related to the order, and

the sequence number includes an orderbook sequence number corresponding to a status of the order.

5. The system of claim 1 , wherein the first matching engine is further configured to execute a rollback process for changing data records stored in the first orderbook according to the status data.

6. The system of claim 1 , wherein

the second matching engine is configured to obtain an orderbook sequence number, and

the first matching engine is configured to verify the orderbook sequence number.

7. The system of claim 6 , wherein the second matching engine is further configured to:

attempt to match the order data in the modified order entry message using the second orderbook while the first matching engine verifies the orderbook sequence number, and

generate the confirmation data when the first matching engine successfully verifies the orderbook sequence number.

8. The system of claim 6 , wherein the second matching engine is further configured to:

attempt to match the order data in the modified order entry message using the second orderbook while the first matching engine verifies the orderbook sequence number, and

rollback changes associated with matching the order data using the second orderbook when the first matching engine fails to verify the orderbook sequence number.

9. The system of claim 8 , wherein the second matching engine is further configured to:

perform an additional attempt to match the order data in the modified order entry message after the changes associated with matching the order data using the second orderbook have been rolled back; and

generate the confirmation data after performing the additional attempt to match the order data.

10. A non-transitory computer readable storage medium storing computer readable instructions that, when executed by a processor of an information processing system including a first subsystem, a second subsystem, and an orderbook memory, cause the information processing system to perform operations comprising:

receiving, via the first subsystem, an order entry message from a first device;

creating a modified order entry message by adding status data to the order entry message, wherein the status data relates to an operating state of the first subsystem;

forwarding the modified order entry message, including the status data, to the second subsystem;

receiving, via the second subsystem, the modified order entry message forwarded by the first subsystem;

processing the modified order entry message by attempting to match order data in the modified order entry message using the orderbook memory; and

generating confirmation data associated with the status data contained in the modified order entry message.

11. The non-transitory computer readable storage medium of claim 10 , wherein the confirmation data is generated by comparing an operating state of the second subsystem to the operating state of the first subsystem based on the status data contained in the modified order entry message.

12. The non-transitory computer readable storage medium of claim 10 , wherein

the second subsystem is configured to obtain an orderbook sequence number, and

the first subsystem is configured to verify the orderbook sequence number.

13. The non-transitory computer readable storage medium of claim 12 , wherein the information processing system is further caused to provide execution comprising:

attempting to match the order data in the modified order entry message using the orderbook memory while the first subsystem verifies the orderbook sequence number, and

rolling back changes associated with matching the order data using the orderbook memory when the first subsystem fails to verify the orderbook sequence number.

14. A method for processing order data, the method comprising:

at an information processing system having a first subsystem, a second subsystem, and an orderbook memory:

receiving, via the first subsystem, an order entry message from a first device;

creating a modified order entry message by adding status data to the order entry message, wherein the status data relates to an operating state of the first subsystem;

forwarding the modified order entry message, including the status data, to the second subsystem;

receiving the modified order entry message forwarded by the first subsystem; and

processing the modified order entry message using the second subsystem.

15. The method of claim 14 , wherein processing the modified order entry message includes attempting to match the order data in the modified order entry message using the orderbook memory of the information processing system.

16. The method of claim 14 , wherein the confirmation data is generated by comparing an operating state of the second subsystem to the operating state of the first subsystem based on the status data contained in the modified order entry message.

17. The method of claim 14 , further comprising:

attempting to match the order data in the modified order entry message using the orderbook memory while the first subsystem verifies an orderbook sequence number, and

rolling back changes associated with matching the order data using the orderbook memory when the first subsystem fails to verify the orderbook sequence number.
