Using EA on separate accounts

Hello -
I have a question about how EA's operate. I have a live and demo account with the same MT4 broker. If I want to test an EA on a demo account, how do I prevent it from attaching to my live accounts when I switch over to the same or different currency pairs? I want an EA to run on my demo account to see how it performs and if I need to tweak some settings, but do not want it to activate any live accounts.

From what I can tell, once an order entry EA has been activated and the various stops and limits are in place, that trade is carried out on your account, even if you shut down the EA, unless you actually close or alter the order.

Thanks

Install a separate MT4.

One install will be for live, the second for demo.

There is a function for this. IsDemo() or something.
You should use this function so that you EA will work only with demo accounts.

if (!IsDemo())
{
return();
}


something like this. I don't remember exactly.

bool

IsDemo()

Returns true if expert runs on demo account, otherwise returns false.

Sample

if(IsDemo()) Print("I am working on demo account");
else Print("I am working on real account");

Thanks for the replies - I can install another MT4 station seems the simplest. If I wanted to go the route of the EA command, how do I do that? Where do I find this info?

Many thanks for the quick help on these boards, its a great forum

It would have to be place in your MQ4 code for the EA.
