1. A method of distributing market data over a network from a sender to a plurality of receivers, the method comprising:
- (a) creating at a computer device in real time and on a per message basis a plurality of extensible templates that each that defines a variable length message structure and includes at least one delimiter that is used to identify a repeated group of information and a field outside of a repeating group that specifies the number of occurrences of the group;
(b) building at a computer device a plurality of market data messages that each include variable length fields separated by delimiters and an identification of one of the plurality of extensible templates that defines the message structure used in the message;
(c) disseminating by the sender over the network a first one of the plurality of extensible templates; and
(d) disseminating by the sender over the network a first market data message that identifies and is structured in accordance with the first one of the plurality of extensible templates;
wherein the computer device in (a) creates the plurality of extensible templates on-the-fly so that attributes can be added and deleted.

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.

12. A 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 steps comprising; (a) creating on the fly and on a per message basis a plurality of extensible templates that each that defines a variable length message structure and includes at least one delimiter that is used to identify a repeated group of information and a field outside of a repeating group that specifies the number of occurrences of the group; (b) building a plurality of market data messages that each include variable length fields separated by delimiters and an identification of one of the plurality of extensible templates that defines the message structure used in the message; (c) disseminating a first one of the plurality of extensible templates; and (d) disseminating a first market data message that identifies and is structured in accordance with the first one of the plurality of extensible templates. - View Dependent Claims (13, 14, 15, 16, 17)

18. A non-transitory computer-readable medium containing computer-executable instructions that, when executed by a processor, cause a computer system to perform the steps comprising:
-
(a) creating on the fly and on a per message basis device a plurality of extensible templates that each that defines a variable length message structure and includes at least one delimiter that is used to identify a repeated group of information and a field outside of a repeating group that specifies the number of occurrences of the group; (b) building a plurality of market data messages that each include variable length fields separated by delimiters and an identification of one of the plurality of extensible templates that defines the message structure used in the message; (c) disseminating a first one of the plurality of extensible templates; and (d) disseminating a first market data message that identifies and is structured in accordance with the first one of the plurality of extensible templates. - View Dependent Claims (19, 20)
