I was hoping someone might have done something like this before but I cannot locate it.

Attached is, what I think, a normal Donchian Channel indicator that is also MTF. I'd like this presented as a flat histogram with green when price is above the mid line and red when price is below it. I'd like to keep this working on MTF so its view correctly as well.

If anyone has an existing copy as I've explained, please point me to the right direction. If not, I'd appreciate any help with making what is hopefully a small change.

Thank you,

EJ
