Abstract: The disclosed embodiments relate to implementation, such as by a message processing system architecture, of a message handling system and/or protocol which mitigates optimistic messaging behavior. As used herein optimistic messaging behavior may at least refer to the transmission, in whole or in part, of a message, or of one or more messages of a sequence thereof, to a receiving system, such as the system implemented by the disclosed embodiments, prior to the sender determining that the message(s) is/are desired, alone or in conjunction with subsequently canceling or otherwise invalidating the message(s) once it has been determined that it is not desired. The disclosed embodiments mitigate such behavior by detecting and taking action with respect to these types of messages to deter optimizing behavior which may or may not be manipulative, while maintaining reliable message handling under increasing processing loads with minimal impact on users being able to send messages to the system.

Abstract: Systems and methods for controlling use of a credit pool in connection with electronic trading in a plurality of product groups via a set of match engines are described. Credit data indicative of a current magnitude of the credit pool is obtained. A plurality of allocations of the credit pool are determined, based on the credit pool, across the plurality of product groups. For each allocation of the plurality of allocations, allocation data indicative of the allocation is provided to a respective credit controller of a set of credit controllers. The respective credit controller is disposed at a respective match engine to which a respective product group of the plurality of product groups is assigned. The use of the credit pool for an incoming order in a respective product group is thus limited in accordance with the allocation data provided to the credit controller at the respective match engine.

Abstract: A optimization processor in a data transaction processing system receives an electronic data multiple transaction request message including multiple electronic data transaction requests, and determines whether some of the electronic data transaction requests should be routed through or bypass transaction integrity modules designed to detect and mitigate undesirable object conditions. The optimization processor may also determine whether some of the electronic data transaction requests should be routed through or bypass transaction processing modules designed to match or attempt to match electronic data transaction requests. The optimization processor may, in one embodiment, rely upon previous decisions made by the modules. The optimization processor may also access data structures storing information about a current environment state to determine whether an electronic data transaction request should be routed through the time consuming transaction integrity and transaction processing modules.

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.
