The Lucas Intervals tool is similar to the Fibonacci intervals, with a slightly different starting sequence. Once started, it uses the Fibonacci calculation (add the two previous numbers to get the next) to calculate the interval lines.


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

Delete: Deletes the tool from the chart.



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

Show Dates: Displays / Hides the date label for each interval that appears on the chart.

Extend Lines: Check this box and the Lucas Interval lines will automatically extend from the top to the bottom of the chart. Uncheck this box to manually define the length of the interval lines. Click on one of the small squares that appear on the tool when selected, and then drag that square up or down in order to set the line length.

Line Over All Views: Check this box and the Lucas Interval lines will extend to display over any tools that are displayed in a separate indicator window, for example, Volume.

Forward Intervals: Check this box for the intervals to be calculated ‘forward’ of the nominated start date.

Reverse Intervals: Check this box for the intervals to be calculated and displayed ‘before’ the nominated start date.

Series Style: Sets the Series style used at which to count the Lucas intervals. The Traditional method counts all the Lucas numbers from the originally selected bar, the Continuous option counts each range beginning from the first bar and then from the next Lucas number of bars away from the selected bar.

Line Width: Allows you to adjust the width of the interval lines. Moving the slider bar to the right increases the thickness of the line.

Line Colour: Allows you to select the colour of the Interval lines. Clicking on the drop down arrow will display a colour swatch. Locate the desired colour and left-click it once to select it.
