The trading techniques by W.D. Gann are widely seen as innovative and are still studied and used by traders today. He used angles and various geometric constructions. Gann angles divide time and price into proportionate parts and are often used to predict areas of
support and resistance, key tops and bottoms and future price moves. The method is based on the notion that markets rotate from angle to angle and when an angle is broken, price moves towards the next one. Several angles together make up a Gann Fan.
The angles are drawn from the main tops and bottoms while the chart is scaled appropriately to ensure the market has a square relationship. The most noteworthy angle is the 1x1 or the 45° angle, which represents one unit of price for one unit of time. A change in the direction of price is expected when the market reaches an equal unit of time and price, up or down. TradingView has a smart drawing tool called the
Gann Fan to apply several Gann angles to the chart and other tools like the
Gann Box and the
Gann Square to visually identify key levels on a chart.
