All these signals can be processed by the EA, so we can assume that the problem is with connecting the app to the EA.
Please check if there’s a message in MT4 in the Experts tab – “New client connection”. This confirms the connection of the EA to the app, and also your account number should appear in the app in a green rectangle. Otherwise, please try using another MT4 ID by selecting it in the EA’s inputs and in the app.
Also, if your broker is using a prefix or suffix to the symbols’ names, like “EURUSD.r”, you need to adjust the inputs in order to recognize the symbols.
Let us know if this helped, or you can send us some screenshots of the app to firstname.lastname@example.org, MT4 and the inputs you have set so we can investigate further,
