Patent ID: 7509284

Claim:
A method comprising the steps of: receiving from a first trader a first warning limit specified against a second trader; receiving from the second trader a second warning limit specified against the first trader; receiving at a trading system a first order from the first trader; receiving at the trading system a second order from the second trader, in which the first order and the second order result in a pending trade between the first trader and the second trader; determining that execution of the pending trade between the first trader and the second trader causes at least one of the first warning limit and the second warning limit to be exceeded; and processing the pending trade between the first trader and the second trader, in which processing the pending trade comprises one of: the trading system rejecting the pending trade, the trading system executing in part the pending trade such that the executed in part trade does not cause the first warning limit nor the second warning limit to be exceeded, and the trading system executing in full the pending trade; and based at least in part on determining that execution of the pending trade between the first trader and the second trader causes at least one of the first warning limit and the second warning limit to be exceeded, displaying to the first trader via a workstation a prompt as to whether the first trader does or does not want to subsequently trade with the second trader.
