Instructions for Updating NinjaTrader Strategy

These instructions guide you through removing an old strategy assembly and installing a new strategy zip file in NinjaTrader 8. Please follow each step carefully to ensure a smooth update.

Step 1: Remove the Old Strategy Assembly

  1. Close Open Charts: Ensure no charts using the old strategy are open. If needed, close your current workspace (File > Workspaces > Close Workspace) and open a new one (File > Workspaces > New Workspace) without saving changes.

  2. Access the Remove Assembly Tool:

    • From the NinjaTrader Control Center, go to Tools > Remove NinjaScript Assembly.

  3. Select the Old Strategy:

    • In the pop-up window, locate the assembly corresponding to the old strategy (e.g., named after the strategy or vendor).

    • Click to select it. Hold Shift to select multiple assemblies if applicable.

    • Click Remove.

  4. Manually Remove Individual Strategy (if not listed in assembly):

    • If the strategy does not appear in the Remove NinjaScript Assembly list:

      • Go to New > NinjaScript Editor.

      • Double-click the Strategies folder in the right pane.

      • Right-click the strategy you want to remove and select Remove.

      • Confirm the removal when prompted.

  5. Restart NinjaTrader:

    • Close and reopen NinjaTrader to ensure the assembly is fully unloaded.

Note: If you encounter a warning about the strategy being in use, ensure all charts or workspaces referencing it are closed. If the strategy still doesn’t appear in the assembly list or editor, contact support for assistance.

Step 2: Import the New Strategy Zip File

  1. Download the New Zip File:

    • Save the new strategy zip file to an easily accessible location (e.g., Desktop or Downloads folder). Do not unzip the file.

  2. Import the Zip File:

    • Open NinjaTrader 8.

    • From the Control Center, go to Tools > Import > NinjaScript Add-On.

    • In the file explorer window, navigate to the location of the new zip file.

    • Select the zip file and click Open.

    • Acknowledge any warning messages about installing third-party add-ons by clicking OK.

  3. Restart NinjaTrader:

    • Close and reopen NinjaTrader to complete the import process.



Member feedback and tips:







good deal- yes thanks for the write up with the instructions, very helpful. If anybody has that problem again, open script editor, and look at the orange and red code that has errors once you compile, you can find the file name with the code above and they can do a explorer specific file search on the entire c: drive ofthe file name.

Thanks for all you do, we are so grateful!
