Transactionally deterministic high speed financial exchange having improved, efficiency, communication, customization, performance, access, trading opportunities, credit controls, and fault tolerance

A system comprising:

• a processor and a non-transitory memory coupled therewith having computer readable instructions stored therein configured to cause the processor to:
• determine a particular prior state of an electronic marketplace to be reproduced, wherein the particular prior state comprises a cumulative result of processing of incoming transactions previously received by the electronic marketplace over a prior period of time;
• retrieve a subset of data previously stored in the memory representative of at least a subset of the incoming transactions previously received by the electronic marketplace over a specified prior period of time for execution thereby, the processing of each of which causes a change in at least an intermediate state of the electronic marketplace, for which sequential processing of at least a subset thereof would cumulatively result in reproduction of the particular prior state;
• identify a pattern of two or more subsets of transactions of the retrieved subset of data which indicate that the particular prior state would be reproduced by the retrieved subset of data;
• accumulate data indicative of subsequently received transactions in a memory coupled with the logic component, wherein the memory has a capacity to store a limited number of received transactions such that, after the capacity of the memory has been reached, as a new transaction is received, the data indicative thereof is stored in the memory in place of the data indicative of the oldest transaction stored therein;
• and
• compare, periodically, the currently accumulated data with the identified pattern to detect when at least a portion of the identified pattern occurs.

A computer implemented method comprising:

• determining, by a processor, a particular prior state of an electronic marketplace to be reproduced, wherein the particular prior state comprises a cumulative result of processing of incoming transactions previously received by the electronic marketplace over a prior period of time;
• retrieving, by the processor, a subset of data previously stored in the memory representative of at least a subset of the incoming transactions previously received by the electronic marketplace over a specified prior period of time for execution thereby, the processing of each of which causes a change in at least an intermediate state of the electronic marketplace, for which sequential processing of at least a subset thereof would cumulatively result in reproduction of the particular prior state;
• identifying, by the processor, a pattern of two or more subsets of transactions of the retrieved subset of data which indicate that the particular prior state would be reproduced by the retrieved subset of data;
• accumulating, by the processor, data indicative of subsequently received transactions in a memory coupled with the logic component, wherein the memory has a capacity to store a limited number of received transactions such that, after the capacity of the memory has been reached, as a new transaction is received, the data indicative thereof is stored in the memory in place of the data indicative of the oldest transaction stored therein;
• and
• comparing, periodically by the processor, the currently accumulated data with the identified pattern to detect when at least a portion of the identified pattern occurs.

A non-transitory system comprising:

• means for determining a particular prior state of an electronic marketplace to be reproduced, wherein the particular prior state comprises a cumulative result of processing of incoming transactions previously received by the electronic marketplace over a prior period of time;
• means for retrieving a subset of data previously stored in the memory representative of at least a subset of the incoming transactions previously received by the electronic marketplace over a specified prior period of time for execution thereby, the processing of each of which causes a change in at least an intermediate state of the electronic marketplace, for which sequential processing of at least a subset thereof would cumulatively result in reproduction of the particular prior state;
