Moving Avg. on chart when backtesting??

1. Start visual test, pause, put indicators on chart, save a template. Next run you can just add the template. Only problem is if the parameters the EA uses changes, chart won't reflect that.
2. Have EA put lines on chart https://www.mql5.com/en/forum/130907
   

WHR.. Thanks for the reply.. Yes, it is much easier to save multiple indicators to the template and then load the template..great idea. I'll have to study the idea of actually embedding the indicator inside the EA. I was hoping I had missed something easy... like a line of code at the beginning of the EA to load/use a specific template automatically. It seems like the extra code "inside" the EA may effect how fast it runs and tests... Thank you for your help.

Skip ticks that don't affect the EA. Draw the lines only on new bars. Don't draw in testing.
