This script shows the volume of a given stock, relative to the historical volume within the measurement window, so you can see the volume trending up or down rather than absolute values. I layer this with the "Historical Volatility MA - Layering."
I have removed the slow moving average line and instead combined, so the fast moving average of the volume is now based on the difference between it and the slow moving average. Previously, the difference between current and historical could sometimes cause the slow line to be flattened out.
