Understanding Price Action (Bob Volman)
Naked Forex: High-Probability Techniques for Trading Without Indicators (Alex Nekritin & Walter Peters - worth reading even if you don't intend to trade forex)
Daytrading (Joe Ross) (this is an updated re-issue of an earlier book - "Trading by the Minute", I think it was called)
Trading The Ross Hook (Joe Ross) (I keep coming back to this one again and again, because it's simple and logical and helpful, and the whole concept is based on one of the soundest principles of price action trading, namely "buy the dips in an uptrend and sell the rallies in a downtrend")
Trading Price Action Trends - Technical Analysis of Price Charts Bar by Bar for the Serious Trader (Al Brooks)
Trading Price Action Trading Ranges - Technical Analysis of Price Charts Bar by Bar for the Serious Trader (Al Brooks)
Trading Price Action Reversals - Technical Analysis of Price Charts Bar by Bar for the Serious Trader (Al Brooks)
"Warning": Al Brooks' set of three textbooks is kind of badly written and very badly edited (especially considering who the publisher is), and pretty difficult to plough through, but their content's excellent and was super-helpful to me, so those are a kind of "mixed recommendation": I actually think his online video course is much, much better and more helpful and more approachable, but it's also more expensive (now $350, I think - but that's still very good value, in my opinion, for about 37 hours of instructional videos).
