Gann Planetary Lines


Gann Planetary Lines converts the angle of a selected planet to price, which is then plotted onto the chart. This plot is then repeated every 360 degrees with additional harmonic lines available as an option.

For example, a GPL set to Jupiter will plot a line at $100 when Jupiter’s angle is 100 degrees (on a chart using a Price Unit of 1) and again at $460 (360 + $100). A harmonic of 2 will plot halfway (or 180 degrees) between them (i.e. $100 + $180 = $280) and a harmonic of 4 at $90/90 degrees apart (i.e. $190, $280 and $370).

The GPLs can be plotted forward, reverse, or both from a geocentric or heliocentric perspective.

To apply the Gann Planetary Lines tool to your chart, select the Tools menu located at the top of the Optuma screen.

From the Astro tools, select Gann Planetary Lines.

Left-click on the chart and the Gann Planetary Lines will display on the chart with the default settings.

Actions & Properties


Add to Toolbar: Click this action to add the selected custom Gann Planetary Lines to your custom toolbar.

Apply Settings to All: When multiple Gann Planetary Lines tools have been applied to a chart, page or workbook, this action can be used to apply the settings of the one selected to other instances of the tool. This is a great time saver if an adjustment is made to the tool – such as hiding or adding levels- as this allows all the other Gann Planetary Lines tools in the chart, page or entire workbook to be updated instantly.

Copy Data to Clipboard: Will copy the tool’s values to the clipboard which can then be inserted into a spreadsheet, for example, allowing for further analysis.

Copy Tool: Allows you to copy the selected Gann Planetary Lines, which can then be pasted onto a different chart window.

Move to Back: If the lines of the tool are displaying in front of other tools or indicators clicking this action will move the lines view to the background.

Move to Front: If the lines of the tool are displaying behind other tools or indicators on the chart, clicking this action will bring the lines to the forefront.

Restore Default Settings: Click this action if you have adjusted the default settings of the Gann Planetary Lines, and wish to return to the standard properties originally installed with Optuma.

Save Settings as Default: If you have adjusted any of the Gann Planetary Lines Properties (colour, for example) you can save the adjustments as your new default setting. Each time you apply a new Gann Planetary Lines to a chart, the tool will display using the new settings.

Delete: Delete the Gann Planetary Lines tool from the chart.


Tool Name: Allows you to adjust the name of the tool, as it’s displayed in the Structure Panel.

Use Chart’s Price Unit: By default, the Price Unit for the Gann Planetary Lines is calculated automatically. Ticking this checkbox will use the price unit of the chart in the tool calculation.

Price Unit Style: By default the Price Unit is automatically calculated, changing the setting to Defined allows the price unit to be manually set.

Price Unit: When the Price Unit Style is set to Defined you are then able to manually enter the desired price unit value.

Planet: Sets which planet/planetary body will be used in the calculation of the Gann Planetary Lines.

Geo / Helio / Sidereal: This setting allows you to change the Gann Planetary Lines setting between GeoCentric, HelioCentric, and Sidereal.

GMT Offset: Use this option to adjust the Gann Planetary Lines time zone setting for a specific market. Select the required GMT setting and the Latitude Transits will automatically update.

Coordinate Type: Select between Ecliptic (Longitude & Latitude) or Equatorial (Right Ascension & Declination).

Harmonics: Allows you to set the number of Harmonics that are displayed.

Direction: By default, only the Forward direction is displayed, but can be changed to display only the Reverse or Both directions.

Planetary Line Style: Expands to display the plot properties for the Gann Planetary Lines. The following properties can be adjusted:
  • Line Style - The Line Style property allows you to adjust the type of Gann Planetary Lines displayed. There are 8 options available: Solid, Dots, Dash, Dash Dots, Long Dash, Long Dash Dot, Long Dash Dot Dot, Stippled.
  • Line Width - Allows you to adjust the width of the line for the Gann Planetary Lines. Moving the slider bar to the right increases the thickness of the line.
  • Line Colour - Allows you to adjust the colour of the Gann Planetary Lines.
  • Transparency - Use this slider bar to adjust the transparency of the Gann Planetary Lines. Moving the slider to the left will increase the transparency.

Harmonic Line Style: Expands to display the plot properties for the Harmonic Lines. The properties are identical to those list for the Planetary Line Style.

Tool Transparency: Use this slider bar to adjust the transparency of the tool. Moving the slider to the left will increase the transparency of the tool.

Visible: Un-tick this checkbox to hide the tool from the chart.
