Abstract

Systems and methods are provided for communicating and processing market data. The market data may comprise quotes, orders, trades and/or statistics. A messaging structure allows for adding, re-ordering and/or expanding data, within the printable character set of any language. One or more delimiters are defined and used to delimit data elements within the message structure. The data is interpreted based on templates which may be disseminated prior to the sending of messages and used as an abstraction so that the meaning of data need not be conveyed in the message.

Claims

1. A method of distributing market data, the method comprising:

(a) transmitting from a computer device a first template defining a plurality of fields;

(b) transmitting from the computer device a first market data message having a plurality of fields separated by delimiters and formatted in accordance with the first template;

(c) after (b) transmitting from the computer device a second template defining a plurality of fields and being different from the first template; and

(d) transmitting from the computer device a second market data message having a plurality of fields separated by delimiters and formatted in accordance with the second template.

2. The method of claim 1, further including compiling data to create the first market data message.

3. The method of claim 1, wherein the first market data message comprises a plurality of orders for financial instruments.

4. The method of claim 1, wherein the first market data message comprises quotes and mass quotes.

5. The method of claim 1, wherein the first market data message comprises statistics.

6. The method of claim 1, further including prior to (b) creating the first market data message.

7. The method of claim 1, further including prior to (d) creating the second market data message.

8. The method of claim 1, wherein at least one delimiter is used to identify a repeated group in the first template.

9. The method of claim 8, wherein at least one delimiter is used to identify a repeated group in the second template.

10. The method of claim 1, wherein the length of the first market data message is not the same as the length of the second market data message.

11. The method of claim 1, further including before (c) transmitting from the computer device a third market data message having a plurality of fields separated by delimiters and formatted in accordance with the first template and a length that is not the same as the length of the first market data message.

12. The method of claim 1, wherein the first market data message includes at least one nested group.

13. The method of claim 1, wherein the first market data message includes a price in a binary code format.

14. The method of claim 1, wherein the first market data message includes data in a printable character set format.

15. An exchange computer system configured to distribute market data, the system comprising:

a processor;

a computer-readable medium containing computer-executable instructions that, when executed by the processor, cause the system to perform the steps comprising;

(a) transmitting a first template defining a plurality of fields;

(b) transmitting a first market data message having a plurality of fields separated by delimiters and formatted in accordance with the first template;

(c) after (b) transmitting a second template defining a plurality of fields and being different from the first template; and

(d) transmitting a second market data message having a plurality of fields separated by delimiters and formatted in accordance with the second template.

16. The exchange computer system of claim 15, wherein at least one delimiter is used to identify a repeated group in the first template.

17. The exchange computer system of claim 15, wherein the length of the first market data message is not the same as the length of the second market data message.

18. The exchange computer system of claim 15, wherein the first market data message includes at least one nested group.

19. The exchange computer system of claim 15, wherein the first market data message includes a price in a binary code format.

20. The exchange computer system of claim 15, wherein the first market data message includes a data in a printable character set format.
