The cause of this problem most often are:
- The application of the investor password in the authorization process in Metatrader4, which is used only to monitor the trading. In this situation, in the "Journal" section there will be the status of [Investor mode], meaning "the inability to perform trading operations". To start trading, exit the terminal and run the program again, indicating the valid trading password when authorizing.
- No internet connection. Check the status of the Internet connection on the indicators located in the lower right corner of the terminal. If there is no connection, try entering the terminal again; the cause of the problem may be the choice of the wrong server or the indication of the wrong password.
Please note that the "Buy" and "Sell" keys are displayed in gray in the "New Order" menu and are inactive if you do not specify all of the order characteristics. Also, an order is not opened when the execution of an order of the corresponding volume is not possible for the type of trading account used.
