This alert appears when a stock is trading on significantly higher volume than normal.  Normal volume is based on the average total volume of the stock on several recent days.  Current volume is the volume between midnight and the current time.

This alert can appear multiple times for a stock.  If, in the course of a day, a stock trades a total of 3 1/2 times its average volume, the stock will generate 3 alerts.  The first alert will occur when the stock's volume first gets to its daily average.  The second alert will occur when the stock's volume gets to twice the daily average.  An additional alert is generated each time the current volume crosses another integer multiple of the average volume.

This alert is similar to the High relative volume alert, listed above.  High relative volume is much more precise, looking at only the recent volume today, and comparing it to the normal volume for this time of day.  This alert is better at finding stocks which are trading much, much more than normal.
