  • Definition
  • Interpretation

Also developed by Robert Krausz, the Gann Swing Oscillator complements the Gann HiLo Activator and the Gann Trend Oscillator. It helps define market swings, assisting traders’ decision-making.

The Gann Swing Oscillator can indicate that the market is in either an upswing or a downswing. Its results are plotted on a scale ranging between +1 and -1.

An upswing is defined by two higher highs and is signified when the indicator has a value of +1. Conversely, a downswing is defined by two lower lows and is accompanied by the oscillator reaching a value of -1. Here is how the indicator is visualised on a trading platform.

As mentioned in the previous article, the Gann HiLo Activator, Gann Swing Oscillator and Gann Trend Oscillator are combined in the ‘New Gann Swing Chartist Plan’ strategy.

Specifically, the Gann Trend Oscillator determines the long-term trend, while the Swing Oscillator defines short-term movements. Convergences between the two are traded in their direction. Read about the Gann Trend Oscillator in the next article for additional information and examples of combined usage.
