If you are unable to open a “New Order” window and the “New Order” button on the toolbar is inactive, you have signed in with your investor (read-only) password. In order to trade please use the trader password when you log in.
Inactive “Sell” and “Buy” buttons in the “New Order” window indicate that the volume you specified is invalid. Please bear in mind that the minimum volume is 0.01 lot, and the step is 0.01 lot.
A “Not enough money” error message means that your free margin is not sufficient to open the order. You may need to adjust the volume or deposit to your account.
A “Market is closed” error means that you're trying to open a position outside the instrument's trading hours. You can check the schedule in the symbol “Specifications” or on our website.
