The demo account is valid for 90 days from the day you create the account on MT4 of VT Markets.

On the other hand, a demo account created on MT5 is valid for 30 days, from the last day of last login. In other words, the MT5 login demo account will expire if there is no login activity on it with "Master Password" in 30 days.

If your demo account is expired, you can login to the Client Portal to create a new demo account by clicking "Account" > "Demo accounts" and submit your application.
