Technical
analyst W.D. Gann emphasized the proportionate influence of the time and
duration of market movements as well as the influence of the size of price movements. Gann angles are specific angles used by technical analysts to draw trendlines from market price tops or bottoms. The most important Gann angle is the 45-degree line because it is seen as the perfect balance between time and price. A major
reversal is usually indicated by a break of the 45-degree line.
