Though forex traders can open several accounts at a time to make forex trading convenient for them sometimes you cannot log in to your MT4 account as it shows MT4 INVALID ACCOUNT error.
MT4 invalid account error occurs when a trader can not log in into the Metatrader platform because of wrong login credentials (wrong username, password or server name) or non activated account or closure of CFD and Forex due to holiday time (the market is closed during weekends or holidays). Invalid account mt4 error can be easily fixed if trader type right login credentials during working trading sessions (when the market is not closed) and check is his account is enabled (sometimes account is not activated). Invalid account mt4 app problem can be fixed in the same way as on desktop.
There can be several reasons for the invalidity of your MT4 account.
It can be due to the closure of CFD and Forex due to Saturday, Sunday or any other common holiday as no trading is done these days. So you may not be able to log in to your MT4 account during these days as your account cannot be connected in the off hours of the market.
OTHER REASONS FOR MT4 INVALID ACCOUNT
FOR LOGGING IN A REAL ACCOUNT
REASON 1: THE SERVER NUMBER IS WRONG
While opening the MT4 account a Server Number was sent to you by email. You cannot log in to your account in case the server number selected by you is dissimilar to the one you have registered for.
You can log in to your account by selecting the exact number of servers registered by you while starting the account.
REASON 2: NON-ACTIVATED ACCOUNT
You have to upload a few documents to your broker for your identification and activation of your account to trade and withdraw.
If you have not uploaded these documents then your account will not be activated. You cannot use it and it will be shown as an MT4 invalid account
REASON 3: USE OF OLD APP OF MT4 FOR LOGGING IN
The apps of MT4 are regularly upgraded by brokers. It is invalid to use old apps for trading and withdrawals as information about upgrading the app is sent to all the subscribers through email.
So if you are using an old app even then it will show an invalid account.
REASON 4: USE OF THE WRONG PASSWORD
You might have set a password while opening your MT4 account with your broker.
It will show the MT4 invalid account if you do not remember your password while logging in. You can call your broker to get a password on a temporary basis to operate your account.
REASON 5: ACCOUNT IS NOT USED FOR UP TO 90 DAYS
If you do not use your MT4 account for up to 90 days then your broker will automatically block it even without giving any notice to you.
You cannot log in to your MT4 account if it has zero balance at the time of blocking. In such a condition you will have to open another account to start trading again. But if there is some balance in the account then you will have to pay monthly hibernation charges of $5 to reopen the account. Such situations can be avoided by making small transactions regularly.
FOR LOGGING IN A DEMO ACCOUNT
The reasons for invalidity and their solutions can be the same as in real accounts. But if it shows MT4 INVALID ACCOUNT for not using it for up to 90 days then your demo account will be locked automatically. Once it is blocked you cannot reopen a demo account. You will have to register for another demo account in such cases.
