Does MT4 allow the design of an EA that can be programmed to remove or disable another EA (maybe attached on the same chart)?

Thanks everyone.

Well, there is only one EA per chart, so attaching a 2nd EA removes the first.

As for EAs interacting, the only way to do that is using the GlobalVariables feature, and even then it's a little hairy.

You can also use text files for this. One EA writes, the other reads, vice-versa

Text files work, yes, but wouldn't the whole read/write process cause them to lag?

That answer is, of course: It Depends

We have no idea what this guy wanted to do with two EAs. It sounds like he just wants them to disable/enable each other. That can be done with simple "1" or "0" written to a text file, most likely with little lag.
