There really is this truth and elegance to watching what price has done in the past and where it has done it, and then seeing what traders to with it once price gets here again. Traders are no different than people buying stuff, and hence why Db calls this all an auction market. My ability to read this is lacking, and worse is my ability as to what I'm going to do about it.
You hit the nail on the head when you bring up statistical testing and rigorous discipline. Patterns are much easier to test, but I don't believe have a better win ratio because they fail to take into account the context and even more so, behavior. A pattern has to look perfect, the behavior has some wiggle room I believe and if you're in tune with reading this, you're set. It is after all the behavior that sets up the pattern. If I was to do this all mathematically, I might as well be a hedge fund or quant, which is even way further beyond my means than reading behavior!
