Patent ID: 8924282

Claim:
A method comprising: transmitting, via a processor to a trading system, requests based on at least one trading algorithm, in which the requests include: (i) a bid request or an offer request; and (ii) a request to cancel the bid request or the offer request at a later instance in time, and in which the processor and the trading system are in electronic communication over a network; receiving, via the processor, an indication that the request to cancel was unsuccessful and the bid request or the offer request has been matched; computing, via the processor, a length of time by which the request to cancel was unsuccessful, in which computing the length of time further comprises: (i) receiving a time by which the request to cancel was received and a time by which the bid request or the offer request was matched; and (ii) computing a difference between the time by which the request to cancel was received and the time by which the bid request or the offer request was matched; and adjusting, via the processor, the at least one trading algorithm based at least in part on the computed length of time.
