Method and system for determining modulated volume information for a tradeable financial element

摘要

A method and system for determining modulated volume information for a tradeable element, such as a security or commodity. The invention compensates for normal fluctuations in volume occurring during the course of a trading period, thereby enabling convenient visualization of abnormal volume activity. In one embodiment, the invention involves providing a historical data source containing historical volume information for the tradeable element for a plurality of historical time intervals; obtaining unmodulated volume information for the tradeable element for a selected time interval in the trading period; retrieving from the historical data source selected data representing historical volume information for one or more of the historical time intervals corresponding to the selected time interval; and using the selected data to convert the unmodulated volume information for the selected time interval to modulated volume information for the selected time interval.
