Hi Tamas,

I tried your steps on two computers and was unable to reproduce. Are you deleting this strategy while you still had it open somewhere? Maybe running in Strategies tab or somewhere else?

i will give you a feedback later

Josh,

I checked it again (NT7B10), please test it like this:

- Open NT
- Open SampleMACrossOver in editor.
- Right Click --> SaveAs SampleMACrossOver1
- Build.
- Run Optimizer on SampleMACrossOver1 strategy.
- Save result.
- Close NT.
- Delete SampleMACrossOver1.cs file.
- Open NT.
- Open another strategy.
- Buld.
- Open or delete saved optimizer results SampleMACrossOver1 in Strategy Analyzer.
--> Error

I thing this is not good like this, because practicallyin NT I don't make any file and edit operations (i think like others), only in VS. In NT I only build. If, however I deleted the strategy file long ago, because I didn't need it, then I can't open the saved results of that any more. Which is worse, that I can not delete the result, so more and more gathered.

>> - Delete SampleMACrossOver1.cs file.
You NEVER should do this as it causes inconsistencies in NT as you experienced. ONLY delete "files" by the editor file dialog.

OK, it's clear, thank you.

Only suggestion:

- even if opening does not work, then deleting should work.
- or at least it does not throw unhadled exception.

Thanks for your suggestion. We'll add it to the list of future considerations.

Note: You should hold off manually manipulating the files in <my documents>/NinjaTrader7 to not corrupt NT

I stopped doing that
