Included in Gann Edition Included in Astro Edition


Fibonacci Intervals plots vertical lines on trading / calendar days according to the Fibonacci number series on the chart, allowing you to see this Fibonacci number series displayed visually on the chart. Once a date has been selected, the lines will be plotted automatically from that point. Note - this tool is available in the Gann Tool add-on module only. However, it can be replicated manually the using the Trading Day or Calendar Day Intervals tools and adding interval values.


To add the tool to your chart, select the tool from the Fibonacci tool group, and left-click on the bar on the chart you wish to calculate the tool from. 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 Fibonacci Intervals 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 Fibonacci Intervals 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.

Set Time Alert: Selecting this action will set a Time Alert at the value the Vertical Line is positioned.

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 Fibonacci Intervals to a chart, the tool will display using the new settings.
