Close trades EA

Context:

I am currently operating two EAs, one of them the main one that contains strategies such as: money management, stop loss, and grid

The other is an EA that applies Coverage and Recovery Zone strategy.

What is what I need:

I need a third EA that closes all open trades and cancels all pending trades of the second EA immediately after the first EA closes its trade but closes only the trades of the second EA, not all trades of all pairs and all EAs already. I intend to use it on different currency pairs

That the different EAs can be identified by Magic Number
