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.
