How to operate on an MT4 account (via MQL) without logging in to the account via MT4 terminal?

 

Is there any hacks or tricks to do it?
For example, i have 10 MT4 accounts & i want to send a "trade_open" command to all of em via an EA /dll/3rd party ways. Running 10 instances of MT4 terminal is foolish tbh.

I know Manager api supports transferring/copying of trades across accounts, but i'm looking for an MQL way of doing that.

Reason:
