Backtesting issue

[bio-liucheng]

Dear developer,

I recently installed GOLD_ORB following the instructions provided in the repository. However, I have encountered some issues during retrospective testing with the example Backtesting. Specifically, I was unable to replicate the results as no buy or sell operations were executed.

Additionally, I noticed several warnings during the compilation process, and I am uncertain if these are normal or indicative of a problem.

Could you please provide guidance on how to resolve these issues? Any assistance would be greatly appreciated.

Thank you for your time and help.
