Hi @vareks, can you provide more information about this feature? Something like:

• Usage
• Input/Output
• Investing.com URL with sample data
• Why this is useful
• etc

As well as creating the tests, which is required so that I can check that the functionality that you developed is fully working and all the exceptions are properly handled. Worst case scenario I can tackle the testing part once merged the PR, but I would need more information as requested above.

Thanks a lot for this new functionality! :hugs:
