A trade filtering process for preventing the processing of suspect trades
includes a trade monitoring process for monitoring a trade price
associated with each trade of a specific stock during a trading session.
A trade comparison process, responsive to the trade monitoring process,
compares the trade price of each trade of a specific stock to a known
acceptable price for that specific stock to determine which trades are
suspect trades. A suspect trade filtering process, responsive to the
trade comparison process, prevents the processing of the suspect trades.
