Yes, you can add indicators to chart from mql5 script. It's only available in mql5. Use this function->  ChartIndicatorAdd

ChartIndicatorAdd()

 
Why write and use a script? Just add them to the chart, and you are done.

You can see an example of the indicator [data folder] \ MQL5 \ Indicators \ Examples \ Alligator.mq5 - one indicator draws three graphical plots.

Because this doesn't work in the tester.

Scripts can't be used in the Strategy Tester either, so why wake up an old thread for such an irrelevant comment?
