But if you have bonuses on your account, you may get negative value. In this case you may zero the account balance and use this account in further trading.
In order to zero the account balance, please login to Client's Cabinet, choose the option “My accounts†and click at the button with the arrow in front of the account number (the arrow button is situated below the wrench icon) and after that confirm the changes by answering to your security questions.
