EA for finding other EAs (like Master & Slave)

Dear programmers,

I am looking for an experienced MQL5 programming expert which can deliver a well-written MQL5 EA, delivery with source code. Task is as follows:

The programmed EA (let’s call it "test EA") shall find out if another EA (or script, etc.) is used in the current MT5 terminal. If there is another EA, "test EA" shall check if the found EA is the same one ("test EA") or another one. If this is another one, then all "test EA" shall close instantly. If it's the same, just with another magic number, then everything is fine.

Important for this check is not only to check the name of the EA (because you could easily change the name of the other to "test EA"), but there should also be some additional checks.
Maybe it makes sense that all "test EA" are communicating with each other. Maybe there is another approach possible.

Finally: Whatever the approach, the EA shall work fast and shall consume only a very little RAM. The approach shall be done in a way that it works to 100% safely and another EA (or script) are not running on the terminal.

Thank you for your application.
