W. D. GANN'S MARKET GEOMETRY
As a trader, W. D. Gann was concerned with trading a simple, practical, consistent, and effective market geometry. Gann's core methods of trading market geometry were far less complicated than most commercially taught market geometry.
The trick to implementing these powerful techniques is applying W. D. Gann's Law of Vibration. None of Gann's trading methods will work without the proper numerical vibration for each market. These methods include the work of Luther Jensen.
