Gann Line

Gann Line
The Gann line is a drawing tool based on the analysis methods of W.D. Gann. In his publications around 1929 Gann presented methods based on the premise that the market obeys mathematical - geometrical - laws.

He proposed a relation between the price dimension and time dimension, which construct a price pattern. Thus the idea of constructing trend lines based on angles and time was born.

You can use Gann lines for
  • Marking trends in price movements
  • Searching support and resistance price levels
You can find the Gann line in the Chart Tools group in the toolbar.

Entering a Gann Line

  1. Open a symbol chart.
  2. Click on the Gann line tool in the toolbar.
  3. Click into the chart to set the starting point.
The Gann line is drawn. The default setting of the Gann line is an angle of 45°. This complies to a 1:1 ratio of time and price. The angle results from the property Runs (Rises is a calculated value). Change the Runs value to change the angles. With a Runs value of 2, a 1:2 ratio results.

Editing a Gann Line

  • To move the Gann line, drag the line, i.e. the anchor point, with the mouse (the mouse pointer turns into a hand symbol) and move it freely. Release the mouse button when done.
  • You can duplicate a Gann line by double-clicking on it.
  • When the Gann line is selected, you can edit the properties in the toolbox.
  • To delete the Gann line, right-click on it and select Delete from the context menu. Alternatively, select the Gann line and press the DEL key.


Runs - Here you can enter how many candles/bars a price on the price axis should represent.

Rises - This value is calculated from the Runs value and the line properties when first drawing the Gann line. Will not be adapted when you move or edit the Gann line.

Color - Here you can edit the line color, e.g. to red.

Width - Here you change the thickness of the guide line in pixels, e.g. to "3".

Style - Here you can edit the line style, e.g. set it to "Dot".W.D.Gann Investopedia
