[BUG] Bottom chart is what? always a slope up or slope down. Can't see what it is

[nostitos]

There is no name, No scale, No settings about it.

It's CVD

[nostitos]

Cumulative Volume Delta (CVD)

Still, I don't know why this is there but not customizable. It doesn't even say what it is anywhere. Price is self explanatory, this is not.
