Account type selection during registration under PU Prime UAE is not customizable. By default, your account will be created as a Standard account with MT5 as the trading platform, USD as the account currency, and leverage set at 1:500.
If you wish to use a different account type, currency, or trading platform, you may open an additional account via your Client Portal after your account has been successfully verified.
Additional accounts can only be opened once your account verification is complete.
