Whether or not DbPhoenix has the best material on the subject depends on what you mean by "the subject".
"Trading by Price Action" means assessing the relative strengths of buying power and selling power (or, if you prefer, demand and supply) at support and resistance. It has only to do with the result of the transaction, whether it's plotted on a chart, a digital display, a tape, or the back of an envelope. It has only to do with what is in front of you, independent of you, not with what is in your head, e.g., Bollinger Bands, MAs, Fibonacci levels, calculated "Pivot Points", or even bars or candles.
Books, therefore, aren't going to be of much help. They may point you in the right direction, but you're not going to learn how to trade by PA via a book, even mine. If you learn it at all (and you may not want to if you're a casual trader), you'll do so by spending many, many, many hours in front of a computer screen watching price move (as opposed to reviewing hindsight static charts in which price does nothing).
The following is an excellent example of what trading by PA is all about: price and volume, demand and supply, support and resistance. Clean and simple.
