unhandled exception

[benitin]

Good night.
On March 1, 2024, while in Demo, I got the error that I attached in the file after executing an order. There seems to be a jump in data loading. Furthermore, if I try to access the indicators I get another error that I also attach in another file. Even the option to reload historical data appears grayed out.
I have uninstalled and reinstalled Ninja Trader but to no avail. I would appreciate it if you could tell me how I can resolve this situation.

Hello benitin,

Thank you for the message.

Please use the following steps to rename the database file so NinjaTrader automatically creates a new one:

• Close NinjaTrader
• Go to Documents folder > NinjaTrader 8 > db > NinjaTrader.sqlite, right-click on this file and select 'Rename' and change the name to "NinjaTrader Old.sqlite" and then click off of it anywhere to save the name change
  • Please click here for a video demonstration of how to rename the Database file

Now, please use the following steps to remove all of the old Historical Data from the platform and re-download the data new:

• Close NinjaTrader
• Go to the Documents folder > NinjaTrader 8 > db, this folder holds all of the historical data
  • Delete the following folders:
    • Tick
    • Minute
    • Day
    • Cache
      • Do NOT delete any other files or folders
  • After Deleting these folders, reopen NinjaTrader and it will make New ones automatically.

From here, reopen NinjaTrader and test if the behavior continues.


If the behavior continues after the steps above, please use the following steps to send your log and trace files to the support team directly from your NinjaTrader Platform so we may investigate this behavior further:

Wouldn't it be easier to just say delete the db folder in NinjaTrader?
