I see your use of get_ylim() and set_ylim() but could not find a parameter that would take advantage of this. Seems you use it for volume for this exact purpose.
Such calculation is probably what's already being done: the unleveraged value.
The idea seems to be to swap the current value with the current unleveraged value, so that the actual value curve doesn't spike. The leveraged value would still be accessible.
It makes sense
