MT4 very high technical question

hi guys

if i put an EA (call it EA1) with magic number "123" on a chart (let's say EUR/USD). ok

and if i open another chart EUR/USD and put another EA (call it EA2) with the same magic number "123". ok

when EA1 open an order with is own rule of input, can EA2 affect (let's say with a breakeven input) the order open with EA1, knowing they're both "link"by the magic number of the order?

thank you

Yes you can do this.

Mostly you will use a magic to separate the trades between EAs on the same symbol but you can use it in that way.

Nice

thank you
