SSB yes I think the range is a good method, and then if you further apply if: it has, or does not have volume, as a mental overlay you can interpret it fairly well.
I try to approximate congestion, if there is a lot it will require more volume than if there is a minor amount. I suppose you could use the price x volume overlays which are on many charts to do the same since it shows volumes and ranges.
TY SSB I am always searching out different ideas.
