Abstract

A client device coalesces data received from an exchange, and provides a client application such as a graphical user interface with the opportunity to process fewer, but up-to-date, data updates from an exchange when a large volume of prices becomes available. Accordingly, the trader can be assured of receiving updated information that are fed to the client applications at a rate that is cohesive with that client device'"'"'s processing speed.

Claims

1-20. -20. (canceled)

21. A system for coalescing market data, the system including:

a client device adapted to receive a first market data update from an electronic exchange, the client device adapted to send a notification of the first market data update to a graphical user interface to retrieve market data related to the first market update, the client device adapted to store the first market data update in a data structure, and the client device adapted to update the data structure by coalescing further market data updates in the data structure into a coalesced market data update until the data structure is retrieved by the graphical user interface, wherein coalescing further market data updates includes replacing data related to at least one market data parameter from the first market data update with data related to the at least market data parameter from the further market data updates, and wherein coalescing further includes adding data related to another market data parameter from the further market data updates.

22. The system of claim 21, wherein the client device is adapted to display market data based on the coalesced market data update from the retrieved data structure.

23. The system of claim 21, wherein the client device is adapted to set a flag indicating that the graphical user interface has been notified of a first market data update.

24. The system of claim 23, wherein the client device is adapted to refrain from notifying the graphical user interface when further market data updates are received if the flag has been set.

25. The system of claim 23, wherein the client device is adapted to reset the flag after the graphical user interface has retrieved the data structure.

26. A computer readable medium having stored therein instructions executable by a processor to perform a method including:

receiving by a client device a first market data update from an electronic exchange;

sending by the client device a notification of the first market data update to a graphical user interface to retrieve market data related to the first market update;

storing by the client device the first market data update in a data structure; and

updating by the client device the data structure by coalescing further market data updates in the data structure into a coalesced market data update until the data structure is retrieved by the graphical user interface, wherein coalescing further market data updates includes replacing data related to at least one market data parameter from the first market data update with data related to the at least market data parameter from the further market data updates, and wherein coalescing further includes adding data related to another market data parameter from the further market data updates.

27. The computer readable medium of claim 26, further including instructions for:

displaying market data based on the coalesced market data update from the retrieved data structure.

28. The computer readable medium of claim 26, further including instructions for:

setting a flag indicating that the graphical user interface has been notified of a first market data update.

29. The computer readable medium of claim 28, further including instructions for:

for;

refraining from notifying the graphical user interface when further market data updates are received if the flag has been set.

30. The computer readable medium of claim 28, further including instructions resetting the flag after the graphical user interface has retrieved the data structure.

31. A computer readable medium having stored therein instructions executable by a processor to perform a method including:

receiving by a client device in a first thread at a client device a first market data update for a tradeable object from an electronic exchange;

storing by the client device the first market data update in a shared data structure, wherein the shared data structure is shared between the first thread and a second thread;

notifying by the client device a graphical user interface running in the second thread of the first market data update;

receiving by the client device in the first thread at the client device a second market data update for the tradeable object from the electronic exchange subsequent to the step of notifying;

replacing by the client device the first market data update in the shared data structure with the second market data update before the first market update is received by the graphical user interface; and

retrieving by the client device the second market data update from the shared data structure by the graphical user interface responsive to the step of notifying.

32. The computer readable medium of claim 31, wherein the shared data structure includes a plurality of fields, wherein the first market data update is stored in one of the plurality of fields.

33. The computer readable medium of claim 31, wherein the first thread is a communication thread.

34. The computer readable medium of claim 31, wherein the second thread is a graphical user interface.
