📍Open a new content series: [Financial Column]

This series will cover topics such as theory, practice, cases and practical work related to finance

These contents are my online course notes from the past, present and future

I will keep them anyway, so I will just share what I think is useful and what I have made

I have opened another series before: Technical Analysis Tutorial

Friends who pay attention should notice that I will update a complete system tutorial from time to time

Keep sharing, thank you for your attention~
