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

See also Trading Day Intervals.

The example below shows 30 calendar day intervals from the 2019 high 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.

This is a great time saver if an adjustment is made to the tool - such as line colour - as this allows all the other Calendar Day Intervals tools in the chart, page or entire workbook to be updated instantly.
