You may find that there are coins being held in pending orders, and so they cannot be used. Please note that this means you have opened orders which have not finished, or that a withdrawal is still currently in the operating or processing status. These assets still belong to you, and you can cancel the order before their relative operations finish if you want.

Click Orders--Open Orders referring to below.
Choose All to see all current open orders you set up before. Click "Cancel" for orders you want to stop.
