What is Safe Mode in NinjaTrader?

Safe mode is used when you can't start up NinjaTrader 8. For instance, you try to start it and the program crashes right away and you need to adjust orders.
It's also fantastic for troubleshooting. For instance, if you are having performance issues, safe mode can be really useful since it doesn't load any 3rd party software and can tell you if something that was added could be the cause of an issue.

How To Enter Safe Mode

NinjaTrader and Above

If you are running or above you will have an shortcut in your start menu that will allow you to run NinjaTrader in Safe mode.

Older Versions of NinjaTrader

  1. Close down NinjaTrader 8.
  2. Hold down the CTRL Key, and double click the NT8 icon.
  3. Once NinjaTrader 8 starts, go to Help -> About and verify it says "Safe Mode".
Remember, if NinjaTrader is already running, you will have to close the program down first before you can enter safe mode.

Safe Mode Isn't Working?

If you're having trouble using safe mode you will probably need to re-install NinjaTrader 8. Re-installing NinjaTrader 8 will not harm your configuration as it will just install the program files and not overwrite your existing data.
However, if you want to backup your settings to be sure, you can back up the folder Documents/NinjaTrader 8 which holds all your settings. This is different from the Program Files(x86)/NinjaTrader 8 which holds the program files. Once your Documents/NinjaTrader 8 files are backed up, you can continue with your reinstall.
