Here are the files. Thanks!

Thanks, okey I know these very well. They are the Russ Horn MA system. Let me get home, I suspect I already made something.

Do you want a unified trading view code or a porting to MT4/5?

Great! I only want the indicators merged to use for tradingview. I already have the system for mt4.

Here you go, it's not possible to merge both main chart and panel indicators in one single file , this is the best thing doable.

One script for chart
One script for panel

PS: if I can share a point of view, the system is almost useless.

Could you do me one last favor and add this channel to the chart? thanks again!
