Also called Gann Grid or Gann Angle, Gann Fan refers to the technical analysis tool that is used in the domain of financial markets to study and make forecasts regarding price movements.

The reasoning was that price-time harmony takes place at the 1:1 (45°) level. Here, an increase of one price point takes place for one time unit (per day). Some of the other angles, which include 1:2 (63.75°) and 1:4 (75°) are used to find potential resistance and support levels. The other angles which are considered are:
