You can choose one to five indicators for analysis. In your PRT, you only have to add color zones to get the display shown. You can also remove all lines in the code (at Return) if you prefer to work with a sine curve.
It helps me to stick to my rules. I hope it helps you too and brings money 😉
The revised indicators “myCandle …” and “Opening Range …” and “OutsidebarColorSolo” are coming soon (click on my profile and follow me to stay updated).
