Mike,
I apologize for not responding to this sooner. I don't recall getting an email notification.
Anyway, plotting volume with a moving average is easy enough. Just add the Volume Analysis indicator with a smoothing periods, and add it to the same pane as the Volume (or drag and drop it into same pane after adding).
Regarding the std dev bands....you want to draw bands around this average volume line, correct?....and using the standard deviation of the volume itself?
This would require a custom indicator (and thus the Pro version of I/RT, which you may already have). The syntax for the custom indicators would be:
VMA + STD(VO, 100)
and
VMA - STD(VO, 100)
Here is a chart showing these bands on a 5-min chart of ES (day session only).

I used a 100 period smoothing in the VMA settings.
Let me know if you have any questions.
Regards,
Chad
