Volume Based Donchian

A simple experiment that mixes volume and Donchian's algorithm.
In this version I have implemented a more elegant version of the formula, using the VWMA function instead of spelling out the steps.
I have kept both formulas for educational purposes.

I also plot an Alma Moving Average, how you can see a 16 periods Volume Based Donchian is pretty similar to a 80 period Alma. I think it could be nice stuff if you wanna ask me something write me.
