Time Division of 8ths


An important geometric range division used by Gann in his analysis. By selecting a time range the tool will automatically divide the period into eighths.

To add the tool to your chart, select the tool from the Gann tool group, and left-click on the first bar you want to calculate the tool from. Next, left-click on the bar where you want to calculate the tool to. Optuma will then draw the tool using the default settings.

Actions & Properties


Add to Toolbar: Adds the selected tool to your custom toolbar.

Apply Settings to All: When multiple Time Division of 8ths 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 line colour - as this allows all the other Time Division of 8ths tools in the chart, page or entire workbook to be updated instantly.

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

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

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

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

Save Settings as Default: If you have adjusted any of the tool’s properties (colour, for example) you can save the adjustments as your new default setting. Each time you apply a new Time Division of 8ths to a chart, the tool will display using the new settings.

Delete: Deletes the tool from the chart.
