Triple Octave Support and Resistance Lines


As described in The Law of Vibration - The Revelation of William D. Gann, Tony Plummer explains the relationship between pairs of musical notes in the tonic solfa (ie, Do, Re, Me, Fa, So, La, Ti, Do). Gann used this relationship between the notes to calculate support and resistance levels.

For more information on this tool, please contact Tony at  Helmsman Economics.


To apply the tool to your chart, select it from the Gann tool menu. With the tool selected, left-click once on the chart to choose a starting point and left-click on the chart again to select the end point. With the start and end points selected, move your mouse cursor to the left or right to extend the lines, then left-click again to anchor them to the chart.
