The Circle tool allows you to apply a circle onto a chart, this can be used to identify curved trends in the market. Note that the tool uses the chart’s Time/Price Ratio in its calculation, so you may wish to use the Geometric Circle tool instead.


To add the Circle to a chart:

  1. Select the Circle tool from the Drawing tool group. The mouse pointer will change into a pencil.

  2. Left-click on a point where you wish to start drawing the Circle.

  3. Move your mouse pointer to the second desired point and left-click to place the circle on the chart.

  4. Adjust the tool’s Price Unit as required.

Actions & Properties



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

Apply Settings to All: When multiple Circle 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 Circle 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 Circle to a chart, the tool will display using the new settings.

Delete: Deletes the tool from the chart.
