Hello,our beloved coder and genius person

I find this strategy worked so good and simple.
It's possible to made it as Histogram (Red and Blue) and arrow version with this idea?

This is Donchian indicator actually (Donchian Mid Line period 20 >< Donchian Mid Line period 40) ,im using the midle band of Donchian and applyed crossover rule just like MA do.


Thanks for your great free stuff and helped lot of people who struggle
