Are there any possible ways to know? or have to enable EA, and wait and see.

Does most of the EA function while subscribe to signal?

If it filters on

ORDER_MAGIC

ID of an Expert Advisor that has placed the order (designed to ensure that each Expert Advisor places its own unique number)

long

it will only handle it's own order, otherwise it can filter on

ORDER_SYMBOL

Symbol of the order

string

Then it handles only that currency pair.

or without it handles all orders so like i said, it depends on EA.

Is there a way to check an EA that you didn't code if it filters on ORDER_MAGIC like you said?  Like if you get one that is already in Ex4 or Ex5 state.
