Bad calculation of profit and loss of transaction in USD - page 2

 
Petr Nosek:

You'll have to ask your broker. I suppose you use MT4 provided by your broker, aren't you? Maybe it isn't a good idea.

Yes, I asked them why this is happening. And yes, I use "their" MT4. I tried to use MT4 from Admiral markets, logged into my XTB account and result was the same - wrong as in the beginning so this must be related with broker. Thank you again for your help Petr!
