Hello facuevasm,

This is a database error. Could have trouble pulling previously submitted executions for this strategy instance.

Please ensure you are updated to 8.0.26.1.
Click here to download NinjaTrader

Reset the database.

Remove the instance of the strategy from the chart or Strategies tab of the Control Center and add a new instance.

Hello Chelsea! I have the last version of Ninja, and I also reset the database, and loaded a fresh strategy on a new chart, but Im still watching this messages in the log.
The problem comes when I load my strategy on the chart.....

Please find attached the messages that appear on the log today.. Let me know what could be the problem.

Thank you!

Hello facuevasm,

Are you able to reproduce this error adding a new instance of the SampleMACrossover included with NinjaTrader?

Copy the script to a test script and remove all code that can be removed while still being able to reproduce the error.

Then export the reduced copy and attach to your next post so that I may test. Please ensure you have removed all code that can be removed.
