Did you know that you can track distance between two points by utilizing the Price Ruler feature?
Trend lines have the ability to measure the distance (time and price) and the slope between two anchor points. It can also display a percentage amount to track performance. You can set your selection as the default or as a template, if you wish to use different versions.
To enable the price ruler, right click the mouse over an existing Trend Line and click Edit: Check the corresponding boxes for Price Distance, Percent Distance, Bar Distance and Slope, as needed.
