To more clearly see significant increases in daily volume, what is the best way to code this:

(1) Indicator is the percentage amount the end of day volume is above the 50 day moving average of volume.

(2) Plot a histogram chart of this indicator. The horizontal lowest part of the chart would represent the day's 50 day moving average of volume and the vertical axis would be the percentage amount the day's volume is above the 50 day moving average. Color coding would be the vertical bars as green for days when price closes higher for the day, and red for when price closes lower for the day. Days when the volume does not exceed the 50 day moving average do not need to be seen and can be ignored as blank area with no vertical bars.

Looking at the built-in coding and graphing for volume and a 50 day moving average of volume are not providing enough insight.

Any advice is welcome and appreciated,
