The “Invalid Account” message on MT4/MT5 is commonly caused by incorrect login information, including an incorrect trading account number, password, or server. It may also occur if the account has been inactive for an extended period or has been archived.
Below are some common reasons why MT4/MT5 may display an “Invalid Account” message:
- Incorrect Login Information: The trading account number, password, or server entered does not match the account details.
- Password Is Case-Sensitive: Please ensure that the password is entered correctly, as passwords are case-sensitive.
- Incorrect Server: Please ensure that you have selected the correct server corresponding to your trading account.
- Account Has Been Archived: If the trading account has remained inactive for an extended period, it may have been archived by the system.
- Outdated MT Version: An outdated version of MT4/MT5 may not be compatible with the server. We recommend updating MT4/MT5 to the latest available version.
- Incorrect Account Type or Platform: Please ensure that you are using the correct MetaTrader platform and server for your account type. For example, demo and live trading accounts use different servers.
