Error on executing DB command

[raysinred]

Hi,

I have a strategy that I recently noticed was creating an error message in the log file. The strategy compiles without any issue and even functions correctly, or at least I have not been able to determine any issue with it. The error states.

Error on executing DB command: System.InvalidOperationException: There was an error reflecting type ‘NinjaTrader.Ninjascript.Strategies.NAME

Does anyone know what this is or what may be causing it? I likely would have never noticed it, but I could not get NT8 to save my workspace with this strategy. The inability to save the workspace with this strategy added to a chart is what actually led me to the log file.

I would like to fix this if I can. Does anyone know what may be causing this or where I should begin to look in the strategy to determine the issue?

Thank you,
Ray

Hello Ray,

This might be a missing record in the database.

May I have you update to the latest release 8.1.1.3, and then rename the database?
https://account.ninjatrader.com/download

• Shutdown NinjaTrader
• Open the Documents > NinjaTrader 8 > db folder
• Right click on NinjaTrader.sqlite and select "Rename"
• Rename the file ' Original.NinjaTrader.sqlite'
• Finally, start NinjaTrader

Then add a new instance of the strategy to the chart or strategies tab of the control center and test for the error once more.

Chelsea, thank you. I will give this a try.

Hi Chelsea,

I updated to the latest version of NT, and then renamed the database as you described. But I'm still getting the same error and the workspace won't save with this strategy added to a chart.

Any ideas of what else I could try?

Thank you,
Ray

Hello Ray,

Do you have public types that are not using the XmlIgnore() attribute? (types other than string, bool, int, double, enum)

Hi Chelsea,

I think that was the issue. I was using public instead of private.

I'll let you know if I have any other issues.

Thank you,
Ray
