No. MT4 and MT5 are separate trading systems with independent account numbers and passwords. You cannot use MT4 credentials to log in to MT5, or the other way around.
VT Markets uses three separate sets of login credentials:
- Client Portal / VT Markets App password – Used to log in to the Client Portal and the VT Markets App to manage funds, deposits, and profile settings.
- MT4 trading account password – Used only to log in to the MT4 platform.
- MT5 trading account password – Used only to log in to the MT5 platform.
These passwords are set independently during account creation and cannot be used interchangeably, unless you manually set them to be the same.
