The Trading Day Intervals tool creates a number of vertical lines on the chart based on a user-specified number of trading days from a specified starting point.

See also Calendar Day Intervals.

The example below shows 30 trading day intervals from the 2018 low in green.


To add the tool to your chart, select the tool from the Cycles 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.

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

Apply Settings to All: When multiple Trading Day 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 Trading Day Intervals tools in the chart, page or entire workbook to be updated instantly.

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.
