How about support/resistance?

[klewerclaus]

This is THE best project I know, however, I think it lacks one easy to implement feature:
displaying support/resistance, e.g. this way: https://www.reddit.com/r/algotrading/comments/ccomnl/volume_profile_python_code/

I would be happy to implement it, but I am not sure how to do it correctly - any hints from your side?
