Gann Fan
A set of diagonal lines drawn at specific fixed angles from a significant price point, based on a theory that price and time move in proportional relationships.
A Gann Fan, developed by W.D. Gann, draws a set of diagonal lines at specific fixed angles from a chosen significant price point, based on Gann's theory that price and time move in proportional geometric relationships to each other.
The 1x1 line (commonly drawn at 45 degrees, representing one unit of price per one unit of time) is considered especially significant in Gann's original framework, with the other angled lines used as additional potential support and resistance references. See Kaavon's dedicated Gann Fan article for how the angles are actually constructed.
Examples
- The Gann Fan's 1x1 line is considered the most significant angle in Gann's original framework, representing a balanced relationship between price and time.
- A Gann Fan's angles depend on the chart's specific price and time scaling, which means the same fan can look different depending on how a chart is set up.
