Here's another explanation from another support resource at Trade Ideas: "The min current volume filter (which uses relative volume at the specific time of day) does not work premarket so he is using the filter that does not consider time and because most volume is traded at the beginning and end of day, those increased numbers are factored into the avg candle volume which is less likely to be triggered pre/post market."
The video is very helpful with respect to volume generally and specifically as it applies to your High Relative Volume and Strong Volume Alerts, and to your Daily Volume, Current Volume, Volume Today, and Dollar Volume Filters. Unfortunately, it offers no real insight into the Volume 5, 10, 15, and 30 Filters, and, in fact, its only reference to them, made entirely in passing, appears to describe them incorrectly, at least relative to the information on them at http://www.trade-ideas.com/Help.html.
Perhaps it would be good idea to have someone create a video on these Volume X Filters specifically when the appropriate party has a chance to do it. In the meantime, I appreciate your trying to come up with a better explanation and look forward to hearing more on this when you do.
