3. The system of claim 2 wherein the computer readable instructions are further configured to cause the processor determine a particular prior state of the electronic marketplace to be reproduced, retrieve from the memory the stored data representative of the financial transactions necessary to reproduce the determined particular prior state of the electronic marketplace to be reproduced and simulate execution of the transactions represented thereby to generate a simulated electronic marketplace having the reproduced particular prior state.

4. The system of claim 2 wherein the computer readable instructions are further configured to cause the processor to determine a particular prior state of the electronic marketplace of interest and further evaluate the stored data to identify two or more subsets of financial transactions the execution of which would result in the determined particular prior state of the electronic marketplace of interest.

5. The system of claim 4 wherein the computer readable instructions are further configured to cause the processor to identify one or more patterns of two or more subsets of financial transactions.

6. The system of claim 5 wherein the computer readable instructions are further configured to cause the processor to monitor the receipt of each of a subsequently received plurality of financial transactions and detect when at least a portion of one or more of the patterns occurs therein.

7. The system of claim 4 wherein the computer readable instructions are further configured to cause the processor to identify the one or more patters of two or more subsets of financial transactions using a content addressable memory.

8. The system of claim 4 wherein the particular prior state of the electronic marketplace of interest comprises a substantial change in price or change in price change velocity of a traded financial product as compared with a prior state of the electronic market place to the particular prior state of the electronic market place.

9. The system of claim 2 wherein the computer readable instructions are further configured to cause the processor to allow the stored data representative of one or more of a subset of the financial transactions to be modified to modify the one or more financial transaction represented thereby and simulate execution of the subset of financial transactions, including the one or more modified financial transactions, to generate a simulated electronic marketplace having a state resulting therefrom which may be different then the particular state of the electronic marketplace which would result from execution of the unmodified subset of financial transactions.

10. The system of claim 2 wherein the computer readable instructions are further configured to cause the processor to, for a particular state of the electronic marketplace, determine the stored data representative of all of the financial transactions which contributed to achieving the particular state.

11. A computer implemented method for reproducing a particular state of an electronic marketplace for one or more financial products, the particular state resulting from sequential processing, by a financial transaction processing system, of each of a plurality of financial transactions as they were received from a plurality of market participants, the processing of each of which caused an associated change in at least an intermediate state of the electronic marketplace from a prior state thereof which resulted from a previously received financial transaction, the method comprising:

receiving, by a processor coupled with a memory, each of the plurality of financial transactions and operative to store data representative thereof in the memory, the data being operative to cause the associated change in the state of the electronic marketplace if processed by the financial transaction processing system; and

receiving, by the processor subsequent to the receipt of the plurality of transactions and the storage of data representative thereof in the memory, an indication of a particular prior state of the electronic market place to be reproduced and retrieving a subset of the data stored in the memory representative of only the plurality of previously received transactions the sequential processing of which would cumulatively result in the particular prior state of the electronic marketplace to be reproduced, the processor being further operative to sequentially process each of the plurality of previously received transactions represented by the retrieved subset of data from the memory to obtain the reproduced prior state of the electronic marketplace.

12. The method of claim 11 further comprising determining, by the processor, a particular prior state of the electronic marketplace to be reproduced, retrieving, by the processor, from the memory the stored data representative of the financial transactions necessary to reproduce the determined particular prior state of the electronic marketplace to be reproduced and simulating, by the processor, execution of the transactions represented thereby to generate a simulated electronic marketplace having the reproduced particular prior state.

13. The method of claim 11 further comprising determining, by the processor, a particular prior state of the electronic marketplace of interest and further evaluating, by the processor, the stored data to identify two or more subsets of financial transactions the execution of which would result in the determined particular prior state of the electronic marketplace of interest.

14. The method of claim 13 further comprising identifying, by the processor, one or more patterns of two or more subsets of financial transactions.

15. The method of claim 14 further comprising monitoring the receipt of each of a subsequently received plurality of financial transactions and detecting when at least a portion of one or more of the patterns occurs therein.

17. The method of claim 13 wherein the particular prior state of the electronic marketplace of interest comprises a substantial change in price or change in price change velocity of a traded financial product as compared with a prior state of the electronic market place to the particular prior state of the electronic market place.

18. The method of claim 11 further comprising allowing, by the processor, the stored data representative of one or more of a subset of the financial transactions to be modified to modify the one or more financial transaction represented thereby and simulating, by the processor, execution of the subset of financial transactions, including the one or more modified financial transactions, to generate a simulated electronic marketplace having a state resulting therefrom which may be different then the particular state of the electronic marketplace which would result from execution of the unmodified subset of financial transactions.

19. The method of claim 11 further comprising, for a particular state of the electronic marketplace, determining the stored data representative of all of the financial transactions which contributed to achieving the particular state.

20. A non-transitory system for reproducing a particular state of an electronic marketplace for one or more financial products, the particular state resulting from sequential processing, by a financial transaction processing system, of each of a plurality of financial transactions as they were received from a plurality of market participants, the processing of each of which caused an associated change in at least an intermediate state of the electronic marketplace from a prior state thereof which resulted from a previously received financial transaction, the system comprising:
