This has multiple ways to see Forex sessions as I found both on the main chart and on a separate chart useful at different times so this gives you the benefit of both.
When you want to use this separate from your main chart uncheck it the option "On main chart".
On the main chart we can show:
The legend
Boxes
Labels
Breakout check area
Start & end labels
On any other chart area we can show:
The legend
Horizontal bars representing the sessions.
All objects are color coded and the legend shows the color codes.

The code is structured to easily drop into a bigger system so use it as a lone indicator or add the code to some bigger project you are creating.
Finally, if you find value please do make a comment, give thumbs up etc.
