My NT keep crashing. Nothing new has been added. How can I troubleshoot?

Hello ark321,

Thank you for the message.

To troubleshoot why the platform is crashing, you could begin by opening NinjaTrader in Safe Mode which is like opening to the base version of NinjaTrader and see if the behavior continues.

• If yes, the next step is a completely fresh/clean installation of NinjaTrader and see if it keeps happening.
• If no, then this would let you know it is specific to something that is being loaded in within normal mode. Either in general, or if it is specific to something in that specific workspace.
  • This is explained in much greater detail below.

Please use the following steps to open the platform in Safe Mode and create a "Test" workspace to see if the behaviors continue.

• If the behaviors don't continue in Safe Mode, save the "Test" workspace and then reopen NinjaTrader like normal to the Test workspace and see if the behaviors continue.
• If the behavior hasn't returned, reopen the Original workspace to see if this behavior comes back and is specific to your original workspace.

Safe Mode will prevent NinjaTrader from:

• Loading workspaces and connecting on start-up.
• Loading custom assemblies (i.e. 3rd-party add-ons and NinjaScripts)
• Getting instrument updates from the server

To enable Safe Mode, please use the following steps:

• Shut down NinjaTrader.
• Hold the CTRL key and double-click the NinjaTrader icon.
• Keep holding the CTRL key until you see the Sign in Window then sign in (If the logo is Maroon, hold until you see the Control Center since this is an Older version)
• You may then verify you are in Safe Mode by going to Help -> About.

Once you have opened the platform in Safe Mode:

• Reconnect to your Data Provider
• Go to the Control Center > Workspaces > Click new > Call it "Test" > Click OK
  • Please open a new chart with no custom bar types/indicators/templates and test for issues.
  • Create a small Test workspace using Default NinjaTrader Indicators only and test if the behavior continues.

Does the behavior persist on this "Test" Workspace in Safe Mode?

• If the behavior is no longer happening, go to the Control Center > Workspaces > Hover over "Test" > Click save
• Restart NinjaTrader and open the platform like normal. Click "NO" if it asks to save again.

NinjaTrader should open to the "Test" workspace in Normal mode now:

• Connect to your Market Data and test if the behavior continues while here on the Test Workspace in Normal mode.
• If there are no errors, try opening your original workspace

Do the errors return when you re-open the Original Workspace?

• If yes, this confirms that the unwanted behavior is being caused by something within the original workspace specifically.
• You could either:
  • Remove things from the Original Workspace 1-by-1 until the unwanted behaviors go away and you will know the last thing removed was causing it.
  • Or, continue with the Test Workspace and build it back up 1-by-1 until the behaviors return so you know the last thing added back in is causing the unwanted behaviors
    • Once you narrow in on what is causing the Unwanted behaviors, you could reach out to the developer for further help and information on why it is happening and what must be done to avoid it moving forward.
