I don't know what PricePhysics is, but I did get some useful information from understanding how ProfLogic trades. I spent a some time studying it 5+ years ago and it actually is "logical". One of my systems uses something I learned from him, and I am actually starting to do some discretionary trading based on some of the stuff he posted that has had some moderate success (we'll see how it does in the long run though).
I should say for the record that I don't understand his exact entry and exit methodology, but his stuff that is basically a clearer way to see Dow Theory is helpful. Too bad he makes it so hard to dig past his ego and figure out exactly what he is saying.
