I just finished a great book on the subject of Fibonnaci and geometric patterns. Also covers AB=CD patterns, Gartley 222 patterns and Butterfly patterns in depth, with both intraday and position trading examples.
For each method, they also point out a failed pattern example, and discuss recommended risk management, stops, etc. Most books seem to ignore the fact that patterns fail roughly just as many times as they work.
