to find stocks with increasing volume in the last 10 minutes of the trading session? Thank you.

I don't know if there is a "best way" to do this sort of thing. That said, you might want to try making some sort of "volume surge" type formula comparing the volume of the current bar to the average volume of previous bars and set it to a 10 minute time frame.

The key would be to use this as a sort or if you are going to use it as an EasyScan Condition to create the condition for rank instead of value.

An example of a volume surge type condition might check the ratio of the current bar to the previous 10 bars.

V / AVGV10.1

Or calculate the volume of the current bar as a percentage of the volume of the previous 20 bars.

100 * V / AVGV20.1

Or maybe even calculate the the volume of the current bar as a percent change compared to the average of the previous 38 bars (the rest of the trading day during the last 10 minutes in a 10 minute time frame).

100 * (V / AVGV38.1)

It really doesn't matter what form you use (although the period will matter) as the different forms using the same periods will sort into the same order and rank the same.
