Abstract: The disclosed embodiments relate generally to efficient data encoding and transmission. An encoding system determines an encoding interval at which to encode different groups of related data in a data structure. The encoding interval for each group encoded together optimizes the amount of newly received information that is encoded and transmitted in a continuous, repeating loop.

Abstract: The disclosed embodiments relate to communication of financial messages from an Exchange to market participants whereby messages directed to particular market participants may be consolidated with other messages directed to all market participants and communicated via the same communications medium while preserving the anonymity of those market participants to which messages are particularly directed.

Abstract: Systems and methods are provided for managing electronic messages to ensure fair and equitable distribution of information. Two electronic messages are generated by an electronic trading system. A first message includes relevant details of a change of state in an electronic order book due to a received order from a participant. The second message only includes an order identifier corresponding to the first message. The first message is multicast to all market participants. The second message is privately transmitted only to market participants that may access or act upon the received order as a result of a prior relationship with the participant that submitted the received order. After receiving both messages, market participants that may access or act upon the received order may screen an entire order book so that they may identify which orders in the market are available for that market participant to access or act upon.

Abstract: The disclosed embodiments relate to communication of financial messages from an exchange to market participants whereby messages, or at least a portion of the content thereof, indicative of changes in the market, due to one or more trades between two or more market participants, are structured so as to reduce redundant data therein and prioritize the transmission of that portion of the message which summarizes the event and result thereof. Further, these event reporting messages may further consolidate, or otherwise be combined with, the corresponding directed reporting messages communicated to the particular market participants participating in the reported trade while preserving the anonymity of those market participants to which messages are particularly directed.

Abstract: Message processing is described, in which each of first and second computer systems have a message operator configured to process messages to manage a data structure having a state determined via the processing. The message operator of the first computer system is configured to reroute unprocessed messages to the message operator of the second computer system such that the message operator of the second computer system establishes an order of an input message stream and a current state of the data structure arising from the input message stream. The message operator of the second computer system is configured to, once the current state is established, send the messages of the input message stream to the message operator of the first computer system in accordance with the established order such that the current state of data structure is recreated by the message operator of the first computer system.

Abstract: A computer implemented method for storing and retrieving data elements in a computer memory comprises configuring, by a processor, the computer memory according to a data structure, the data structure including: a data element array including a plurality of sorted data elements, each data element associated with a position in the data element array; and a cluster element array including one or more cluster elements, each cluster element defined by one of one data element from the data element array or a plurality of continuous data elements from the data element array, wherein each cluster element is associated with a cluster code for determining the position of one or more data elements in the data element array, the cluster code correlating each data element defining the cluster element with the position of the data element in the data element array.

Abstract: The disclosed embodiments relate generally to efficient data transmission and receipt. Specifically, the disclosed embodiments provide systems and methods for selectively combining multiple, disparate message types and transmitting same via one data feed. A consolidation system determines whether data resulting from an event can be combined or merged based on pre-determined message characteristics and state or environment information, or should be sent via two separate feeds. The merged message may be backwards-compatible so that data recipient computing systems can easily and selectively decide which portion of the merged data is relevant to the data recipient computing system, only read the relevant portions. Thus, multiple data receivers, which typically consume different message types, can receive and consume the same merged or consolidated message.
