ninjatrader crashes everytime i import ninjascript add on

[corvettecandles]

I cannot import any indicators. in trying to trouble shoot i have deleted all data, uninstalled ninjatrader and reinstalled and restarted fresh and started over, and then tried to import indicators that i know i have had in the past, those still didnt work either. i dont know what to do, when it does this i got this error before and after i uninstalled and reinstalled ninjatrader - "import failed. The NinjaScript Archive File may contain duplicate method names that already exist on your PC, modify a method signature that other scripts were dependent on, or be missing a require file on either your PC or in the import archive."

Hello Corvettecandles,

Thank you for the message.

The error you see when importing the add-on means that there is already a file in the PC defining the same terms or variables that you are trying to import.

• For example, there is already a file within NinjaTrader that says X = 5
  • Then, you are trying to import a NinjaScript that says X = 11
  • Since X cannot equal both 5 and 11, the platform doesn't let you import the strategy and cause more errors.

Since NinjaTrader doesn't create the 3rd party add-ons, we do not have specific information on what files would need to be removed specifically so that your add-ons no longer show errors.


To resolve this behavior, you can either:

• Reach out to the developers of the add-on you are trying to import and get their help finding out which files are in the way and then get their help removing the offending files.
• Or, follow the steps below to remove ALL of the 3rd party add-ons from your platform and then reimport them back in 1-by-1 in the order you want them.

To remove all 3rd party NinjaScript Items from the platform to start fresh:

• Close NinjaTrader
• Go to the Documents folder > NinjaTrader 8 > bin, Right-click on this folder and Rename it to "bin Old" and press Enter to save the name change
• Now we need to Repair the NinjaTrader installation:
  • Go to the Windows Control Panel > Programs and Features > Click NinjaTrader 8 > Click Repair > Click Next through the prompts until finished
• Reopen NinjaTrader and check for compile errors using the steps below:
  • Go to New > NinjaScript Editor > Right-click on the background and Compile to show if there are any errors remaining
  • If yes, take a screenshot of the error messages and include that in your response.

From here, you can reimport your add-ons back in 1-by-1 in the order you want them.

• If the error returns, you would know which add-on was causing the duplicate files issue and you can then reach out to the developer for further information and advice.
  • 3rd Party Disclaimer

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