Patent ID: 7813984

Claim:
A data processor-implemented method of modulating volume information for a tradeable element to compensate for normal volume variation in said volume information during a trading period, said method comprising: (a) storing in a database a historical data source containing historical volume information, having normal volume variation, for said tradeable element for a plurality of historical time intervals; (b) obtaining, from an electronic data source, unmodulated volume information for said tradeable element for a selected time interval in said trading period that contains both normal and abnormal volume variations such that said abnormal volume variation is substantially incapable of visualization by a user due to the presence of said normal volume variation; (c) retrieving from said database storing said historical data source at least a portion of said historical volume information for one or more of said plurality of historical time intervals corresponding to said selected time interval of said unmodulated volume information; (d) providing, to a data processor, selected data representing said portion of said historical volume information for said one or more of said historical time intervals corresponding to said selected time interval of said unmodulated volume information; (e) converting, by said data processor said unmodulated volume information for said selected time interval to modulated volume information for said selected time interval by applying said selected data to remove said normal volume variation from said unmodulated volume information to thereby reveal said abnormal volume variation in said modulated volume information for said tradeable element during said selected time interval such that said abnormal volume variation is substantially capable of visualization by the user; and (f) displaying, on a data display, said modulated volume information having said abnormal volume variation with said normal volume variation removed.
