    Hello Yassine.Chetouani, and thank you for your question. For faster service, please begin a new thread instead of replying to a thread over a year old, even if you are experiencing something similar. Our tracking system sometimes does not notify us of replies to very old threads.

    I would like to see on your system exactly what the path to your NinjaTrader folder is. Can you run this test for me and post a picture of your results?

    • Press the Windows key (to the left of the space bar) and the letter r at the same time
    • Type


      in the box that comes up and press enter
    • Type

      cd %UserProfile%

      in the window that comes up and press enter
    • Next, in the same window, type

      echo %CD%

      and press enter
    • Next, in the same window, type


      and press enter
    • Grow this window vertically so that it can show everything that you typed in

    To send a screenshot with Windows 7 or newer I would recommend using Window's Snipping Tool.
    Click here for instructions
    Alternatively to send a screenshot press Alt + PRINT SCREEN to take a screenshot of the selected window. Then go to Start--> Accessories--> Paint, and press CTRL + V to paste the image. Lastly, save as a jpeg file and send the file as an attachment.

      We understand your time is valuable, and that you may not be able to set aside time for this recommended test. You mentioned

      Please, I do not want to uninstall the platform from the scratch as some friends tried, due to the indicators I have and the history I downloaded

      • Rename your (My) Documents\NinjaTrader 8\db\NinjaTrader.sdf file to something unique. I prefer names that include today's date
      • Rename your (My) Documents\NinjaTrader 8 folder to something else that is unique. I prefer names that include today's date.
      • Use the installer you downloaded to uninstall, and then reinstall, NinjaTrader 8
