I wonder how that compares to the cumulative advancing / declining volume line?  But you are comparing the overall market volume with its average.  I'm wondering if there is an indicator here, % stocks trading above their 200 day SMA volume perhaps?  But that does not take account of direction.  So perhaps the indicator would just be comparing the advancing / declining cumulative volume line against its MA?

I imagine it’s similar to what you see in a cumulative line, but it’s nice to be able to see the individual stocks volume intraday in one place to compare how they are acting compared with the last 50 days volume.
