    Hello Memonic,

    Thank you for the message.

    When we see messages about "Connection Lost", "Slow", or "Unable to reach the server", this normally means that the Internet, Modem/Router, or another program is stopping NinjaTrader from maintaining a stable connection to the necessary servers.

    Please remember that a connection state between NinjaTrader and your broker/market data vendor is not dictated by NinjaTrader.
    • The NinjaTrader application only reports the connection state as it is reported by the API you are connected through.
    • NinjaTrader behaves like a radio receiver in that it receives signals from the connected server. If the signals are not coming through, the underlying broker/market data vendor API reports this to the NinjaTrader application which in turn reports this back to you. Once a loss of connection is reported, NinjaTrader or the underlying API will continuously try to re-establish a connection.

    If you haven't already, please perform the steps below to troubleshoot the local network and narrow in on what could be causing these network/connection issues. Please restart NinjaTrader after each set of steps and try connecting again.
    • Begin by restarting your Modem, Router, and PC to refresh the internet connection.
    • Connect your PC directly to the Modem with an Ethernet cable if possible.
    • Ensure that NinjaTrader has been allowed through the Windows Firewall on all networks. Please follow along with this infographic:
    • Ensure that NinjaTrader has been added to any 'Exceptions' or 'Allowed Programs/Apps' kind of list within your antivirus software.
      • If you need to add NinjaTrader manually, the file path is as follows:
        • This PC > Local Disk (C: > Program Files > NinjaTrader 8 > bin > NinjaTrader.exe
    • If you are using a VPN, turn it Off
    • Clear your DNS
      • Open the Command Prompt by clicking the Windows icon and typing "Command"
      • Select 'Command Prompt'
      • Either copy and paste or type the following command: ipconfig /flushdns
      • Press Enter to make it run

    Reopen NinjaTrader and test if the unwanted connection behaviors continue.


    If you are still losing connection after all of the steps above, you could perform these final two tests we have:
    • If you have a 2nd computer at your location you can install NinjaTrader on, do that and try connecting to the account
      • If the connection is still being lost, that points to the Network/Internet connection
      • If it works, that points to something on the original PC causing the connection loss
    • If you have a 2nd connection at your location like a mobile hotspot, connect to it and then try to connect to your account
      • If it is still being lost on the original PC, this points to something within the PC itself
      • If it works, this points to the original Network/Internet Connection in use

    If you perform all of the steps above and are still unable to connect, there are no further steps that we would be able to recommend as this indicates a problem somewhere further down the network path. If the issue persists after completing all of the steps above, you must contact your ISP or a Network Technician and let them know you are experiencing network connectivity issues to the following IP Addresses and get further help looking into what is preventing the connection.

      My network is stable until the CQG servers


      today The conection has suffered disconnection and re-conection.

      finally the platform is connected but i do not receive information from the CQG servers (my ninjatrader desktop is frozen) but the conexion is on.

        Hello Memonic,

        Thank you for the update.

        For some reason you have a stable connection to the Order Servers while you are repeatedly losing connection from the market data servers.

        From here, you have to reach out to a Windows, PC, or Network specialist who is trained on the WinMTR software and get their help understanding why the behavior is happening and what needs to be done to stabilize the connection to that set of specific servers.

        There are no further settings within the NinjaTrader Platform that would change how the connection works.

          • Once the Username and Password have been entered and the Account Type selected, there are no further settings to adjust the connection settings within NinjaTrader.
          • Once a user clicks to connect, it sends a signal with the Username and Password​ to the necessary servers and it is up to the Internet and pathway to those servers to maintain a stable connection to those servers

        Have you tried connecting your PC to a mobile hotspot and testing if the same thing keeps happening yet?
        • Have you tried a 2nd PC at a different location to see if it runs into the same thing?

        If the connection loss continues, you will have to keep working with a network specialist for further help and information.

        Please let us know if we may provide any further assistance.
