Hello pickles1774,

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

Reopen NinjaTrader and test if the behavior continues.


Please remember the NinjaTrader Forum is a publicly-facing location and the log and trace files can contain private information so they have been removed.

• The Forum is best for asking "How to" or "More information" kind of questions.

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:

• Within NinjaTrader, go to the Control Center > Help > Email Support...
• To: Set this to "Platform Technical Support"
• Subject: Copy and paste the Forum URL
• Attach: Attach a file, picture, or compressed file to share multiple files/pictures
• Body: Include any other information you would like to share on the situation
• Make sure 'Log and Trace files' is checked to include the requested files
  • Send the email

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