CNS - zVol
Normalized volume using the Z-score of a lookback period "X" for each time slice.
So if you are on a 5-minute chart, and it is 9:30am, it calculates the standard deviation of the current volume from the mean volume for that time slice (9:30-9:35am) over X number of days.
It was designed to filter out the noise of volume spikes that occur at market open/close, power hour, etc.
I believe the default lookback period is set to 20 days. I often use 14.
