I always felt I could probably draw market profile, poc, value areas, volume spikes... and many more indicators, by hand just by looking at price. In hindsight of course and I could be wrong sometime, like most of them indicators do.
I would urge you to do some of your own research on Pete Steidelmeyer’s original works. I consider price over time to be far more important than volume. The time component is huge for me. The more time that an instrument spends at a particular price range, the more universally accepted the valuation. Hence the equilibrium and non-equilibrium states in MP. The last price print is a distillation of all collective knowledge from the entire universe of market participants about that particular instrument. And better informed traders don’t let a mispriced instrument stay that way for long.
