[FT]volume confirmation

I was inspired by an article talking about volume confirmation on breakouts. I find volume in isolation to be misleading at times. But I do like the concept of VWAP. What if you had a moving average influenced by volume ( VWAP ), and another moving average not influenced by volume ( SMA ) both calculated using the same price inputs and period length. If you compare the two and take their difference, the resulting histogram would be just the volume influence. This is not tested or vetted in any way. Maybe it'll inspire someone else to do more with it. I made it into a percentage scale, just to potentially better show the context of the range.
Enjoy.
