Use the Official Price Limit Data for Chinese Stocks
Summary
This BigQuant question addresses how to identify a Chinese stock’s daily upper and lower price limits when floating-point calculations differ from exchange prices. The suggested method is to read the platform’s limit-price data source for Chinese A-share stocks, which supplies limit prices directly. Using the stored values can avoid relying on a separately calculated price when checking whether an opening price reaches a limit.
The discussion states the data source to consult but does not show sample records, field names, or a full comparison procedure for classifying an opening price as limit-up or limit-down. It also does not explain coverage across security types or market-rule changes. The material is a narrow data-handling tip rather than a trading strategy, and it gives no empirical performance evidence.
Key ideas
- Read the platform’s Chinese A-share limit-price data source to obtain daily limit prices.
- Using supplied limit prices can avoid discrepancies from independently calculated floating-point values.
- The thread does not provide fields, examples, or a complete opening-price classification procedure.
