You can't copy MT5 signals onto MT4. They use different trade operations.
You would need to create or use two seperate EAs to translate and copy the trades across to MT4, one running on the MT5 account and another on the MT4 account.
However, if you say that you can't use EAs on the MT4 account, then it will not work.
Nice to know about that!I really can't use EA, i need some way to inject the order by another way.
Does the broker block EAs by looking at the magic number or by some other method?
If it is by magic number, then use the magic number "0" which is the default for manual trades!
Also, try to see if a Script will work instead of an EA!
Yes but a script runs the code once and then disappears so its a one time action unless you deliberately lock it into a while loop.
