Detection and mitigation of effects of high velocity value changes based upon match event outcomes

A system comprising:

• a computer processor coupled with a memory, the computer processor specifically configured to:
• determine, automatically based on a current state of a data transaction processing system operative to automatically process electronic data transaction requests as they are received against previously received electronic data transaction requests which results in at least one change to data indicative of a state stored in a data structure maintained by the data transaction processing system, a degree by which the processing of a received electronic data transaction request will change the state of the data transaction processing system, and assigning a comparison value based thereon;
• identify, upon elapse of two or more time intervals, a comparative value;
• and
• determine one of that a first difference between the assigned comparison value and the comparative value of an earlier of the two or more time intervals deviates from a first threshold value, or that a second difference between the assigned comparison value and the comparative value of a later of the two or more time intervals deviates from a second threshold value;
• and
• prevent, automatically based on the determination, subsequent changes to the state of the data transaction processing system by preventing processing of electronic data transaction requests received thereby.
