Also prefer to deposit the necessary funds into your MQL5 account first and then use the MQL5 way of payment to complete your purchase.
I want to subscribe to my first signal in the win2012 r2 VPS. When selecting the MT4 signal to follow the Metatrader 4 terminal opens and asks payment method ...but paypal/VISA/MQL5 all give erros as browers seems to be to old ...
I can't find an option to subscribe ...how do you guys to that ????
