How to create a new Stock Pool (Market)

❓ Questions and Help

How can I create a new Stock Pool (Market) in Qlib and define a specific set of stocks? For example, how can I classify certain stocks under a category similar to CSI 300?"
I have checked the documentation, but it seems that there is no relevant information. If there is, could you please provide the exact link? Thank you!

Thank you for your response! Following the link provided, I have successfully converted the collected custom data from CSV format to Qlib format. However, when I attempted to process the data and calculate market information using the formula 'Mask($close/Ref($close,1)-1, "sh000906")', I encountered an issue. How should I specify the market information for the custom data?Such as "sh000906".
Thank you!
