I've found or rediscovered Joe Ross's work based solely on price action. His principles are timeless in my opinion, and there is no vagueness about his definitions of chart actions. Add to that a rock solid trading method and you have, well, dynamite.
Here's a link to his work called Electronic Trading TNT I, Gorilla Trading Stuff:

His methods have somehow found their way into the public domain. I'm not sure how that happened, but I'm greatly appreciating being able to read his no-nonsense, easy to understand methods. Any trader can benefit from an understanding of Joe's work.
