Abstract: A computer implemented method for controlling operational states of a hardware matching processor includes monitoring, by a circuit breaker, incoming electronic data transaction request messages to the hardware matching processor; dynamically defining a range of values as a function of values included with electronic data transaction request messages received during a rolling lookback window; detecting that an incoming electronic data transaction request message contains a value outside the range of values; transitioning the electronic data transaction processing system into a pre-open state for a predetermined period, thereby preventing the hardware matching processor from matching incoming electronic data transaction request messages; calculating a pre-open value at an end of the pre-open state; and re-opening the electronic data transaction processing system at the calculated pre-open value, thereby allowing the hardware matching processor to match incoming electronic data transaction request messages.

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.
