W.D. Gann’s 28 Trading Rules

William Delbert Gann (June 6, 1878 – June 18, 1955) or WD Gann, was a trader who developed the technical analysis tools known as Gann angles, Square of 9, hexagon, Circle of 360 (these are Master charts). Gann Market forecasting methods are based on geometry, astronomy, and astrology, and ancient mathematics. Opinions are sharply divided on the value and relevance of his work.Gann wrote a number of books on trading.

W.D. Gann described the use of angles in the stock market in The Basis of My Forecasting Method (1935). Calculating a Gann angle is equivalent to finding the derivative of a particular line on a chart in a simple way. Each geometrical angle (which is really a line extended into space) divides time and price into proportionate parts. The most important angle Gann called the 1×1 or the 45° angle, which he said represented one unit of price for one unit of time. If you draw a perfect square and then draw a diagonal line from one corner of the square to the other, you have illustrated the concept of the 1×1 angle, which moves up one point per day.

There has been a general disagreement whether he made profits by speculation himself. However, his famous Ticker Interview shows that his claim to profits was as real as his documented forecasts.
