Hello johnnybegoode,

Thanks for your post.

My first thoughts on that error would be that there is an issue with the database where new entries are seen as duplicates. I would suggest to rename your database file and test your strategy again to see if the issue persists. (Close NinjaTrader, Navigate to Documents/NinjaTrader 8/db/ and rename NinjaTrader.sdf to NinjaTraderOLD.sdf.)

If you are continuing to see issues with one strategy but not with others, I may suggest to compare the strategy against a working version, and to comment out sections of code to identify what the cause is. Since the database keeps track of Orders and Executions, you may wish to look at Order handling in your script and if you are using OnOrderUpdate/OnExecutionUpdate, to model after our SampleOnOrderUpdate strategy.

Please let me know if you are continuing to see issues after taking these steps.
