One EA or Script to run another EA to all symbols

[raven.chrono]

Good Day.

Is it possible that one EA or Script can call another EA to all the Symbols?

Thanks

No. One EA per chart

This works with indicators you can try it with EAs.

Load up 1 chart, load up EA. Save template as default.tpl

Run this script to open all other symbols (make sure DLL calls enabled in options).

Remember when you quit, unload one EA and save the default.tpl again.
