Connection button red

[Ziklag]

Hi, see attached - what causes Nt8 to disconnect and turn the connection button red?

Hello Ziklag,
Thank you for the question.

If the Connection Status Circle is Red, that means the platform has lost connection to the Order Server.

• Please see the following link for more information on what the different colors correlate to for the Connection Status circle:
  • https://ninjatrader.com/support/help...status_bar.htm

Normally this would mean that your Internet, Modem/Router, or another program is stopping NinjaTrader from maintaining a stable connection to the necessary servers.


Please know 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.

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.

Next, ensure that NinjaTrader has been allowed through the Windows Firewall on all networks. Please follow along with this infographic:

• Click here to see the infographic on allowing NinjaTrader through the Firewall

Ensure that NinjaTrader has been added to any 'Exceptions' or 'Allowed Programs/Apps' kind of list within your antivirus software.

Next, ensure that your computer is not turning off your Network Adapter to conserve power:

• Right-click on your Start button
• Select 'Device Manager'
• Expand 'Network Adapters'
• Right-click on your Network Adapter and select Properties > Power Management
• Uncheck 'Allow the computer to turn off this device to save power' option
• Click 'OK' to save the changes
• Do this for all Network Adapters
  • Click here for a video on how to check this setting

Finally, 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 continue using the platform.
