Blank-backtests-screen

The will happen by design if you don't have any Performance Visualizers checked:
1. Preferences (F1) > Backtest > Performance Visualizers
2. Check desired.
3. Save the Workspace (or Default Workspace)

The new selections will take effect when you open the Strategy in a new Window.

Are there any errors reported in the WL9 log file?

Thanks, I will check that when this happens again.

It happens again, so here is an update (WL9 Build 13):

1. All Performance Visualizers are already checked in Preferences > Backtest > Performance Visualizers, and I opened the Strategy in a new window. The Backtest Results tab is still completely blank after Run Backtest.
2. I noticed that the VisualizerOrder line in %APPDATA%\WealthLab9\Settings.txt still contained "Weights" but not "Holdings" (which is what Preferences shows now). I closed WL9, removed that line and restarted. No change, still blank.
3. Regarding the log: I could not find a log file in %APPDATA%\WealthLab9. Do you mean the in-app Log Viewer, or is there a log file somewhere else? Please tell me where to look and I will post the errors.

Select Tools, Log Viewer from the menu, any exceptions reported there? Can you send a screen shot of your backtest preferences with the Visualizers section visible?

Nothing is logged.
Could you not simply ask Claude Code what is the issue? Maybe AI find the issue.

Please post a screenshot of Preferences > Backtest .

Would you be open to a support Zoom call? You're the only customer reporting this so it could help it we and the AI could observe your session on Zoom to help troubleshoot. If you're willing, write to us at support@wealth-lab.com.

Here is a screenshot of preferences backtest:


For zoom call: I will send you a video, and if it still doesn't help you, we can make a zoom call today or next week.
