Controlling multiple EA inputs from an outside source

[Austin John Villarico Salvador]

Is there a way to program EA so that its internal/external variables may be changed by something we've put online?

For example, If we're running multiple trading accounts with the same EA, could we code it so that the EA changes into "SELL ONLY"/"BUY ONLY" with one click from an external source?

I'm fairly new to MQL4/MQL5, I hope someone can help.

Thanks

Yes you can if the EA is coded correctly to do that, but not by changing the external variables.
