MT4 Script that closes all positions and orders from only one particular EA out of multiple EAs

I need a script that closes all positions and orders from only one particular EA out of multiple EAs.

I run several of the same EAs at one currency. Each of them has a different magic numer, of course. Every EA opens a lot of multiple orders and positions. The scipt should close all orders and positions of the very EA I drag the script onto and leave all the other orders and positions from the rest of the running EAs untouched.

After closing all positions and orders those EA should continue trading.
