If it is exactly the same problem, your broker's MT4 server is the problem. Demo servers should be separate from Real servers.
Thank you AndrewAMD
Surprisingly I finally got it to work after removing expert in MT4 and load it again a couple of times and playing with it. It's not very handy i take it.
By the way I used TradeTest script in a Demo account and I was able to open positions just for test. But in a Real account with $200 balance I got this error:
Trade: TradeTest EUR/USD 2019-01-26
Buy Long EUR/USD
Error 075: (EUR/USD::L) - can't open email@example.com at 06:34:47
I read somewhere that there is $7000 balance in real account limitations but I don't have that kind of money in my account!
What am I doing wrong?
