Dusan,
> It won’t run the backtest, it just stays on initial balance.
The reason is that the MT Tester does not load enough historical data. You see that the test starts in January.
Most probably, you have the tester set to: “Date: Last month”
Please select the “Custom period” option and set for “start date” the date you see at beginning of the FTMO App chart. Set the current date for the “end date”.
Please try again and send us a note.
