Ninja won't launch

[Kabzy]

Hello, I'm experiencing a problem when launching ninja8.
Once the loggin and password have been entered, the application remains stuck on the animated logo sequence.
Nothing launches after that. I've tried uninstalling and reinstalling the software with no success, the problem remains the same.
I keep getting stuck at the logo phase, forcing me to close the application each time via the windows task manager.
Clearing the cache and history didn't change anything, nor did renaming the UI.xlm file to UIOld.xlm after a few searches on the forum.
My version of Ninja seems to be 8.1.2.1.
Thanks for your help

Best regards.

Hello Kabzy,

Thank you for the message.

It is possible a 3rd party add-on is preventing you from opening the platform.


Please use the following steps to open the platform in Safe Mode without any add-ons loading in 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.

Please let us know if the unwanted behaviors continued while opening NinjaTrader in Safe Mode or to the "Test" workspace in Normal Mode.

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

Thank you for your reply.
I have indeed managed to open ninja in no-fail mode, the problem must probably come from the bad coding of one of my tools installed on my main workspace. It's going to take a long time and a lot of effort to eliminate the problem, but at least I'll be able to access the platform again.
If I manage to find it, I'll post it here, which will probably help someone.

Best regards.

I have the same exact problem just happened to me today

Hello yahya vaid ,

Thank you for reaching out.

Did you try the steps advised above?

Most likely you are an Apex Toolkit user who needs to update their scripts.

If you want to continue using the Apex Add-ons and indicators, you will want to reach back out to Apex for further help and information on updating the toolkit so you can use the platform with their software again.

• 3rd Party Disclaimer

Otherwise, you will need to remove all of the Apex add-ons from your platform for it to be able to open again.

• First, make sure NinjaTrader is fully closed and not in the background:
  • Right-click on the Windows Start Icon > Click "Task Manager"
  • Click on "More details" to expand the window. If it says "Fewer details", ignore this step, it is already showing More
  • Once NinjaTrader is highlighted in blue, click on the "End Task" button
    • If you don't see it, then it is already closed you are ready to move to the next step
• Now, remove the Apex Add-ons:
  • Go to the Documents Folder > NinjaTrader 8 > bin > Custom
  • Scroll down and then Remove all of the files that have the word "Apex" in them
    • You can either drag them out of this folder and drop them on your Desktop
    • Or, highlight and Delete them.
      • Do not Delete or remove any other files from here.

Once all of the Apex files have been removed, try opening NinjaTrader again and you should be ready to go.

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