Chinese Stock Screening with Limit-Up Patterns and Afternoon Inflows

Summary

This Chinese equity screen combines a daily price-range threshold, exclusion of stocks marked ST, a five-session price-high condition, and afternoon large-order net inflow. It is framed as a way to find stocks with buying pressure, with selection intended before 10 a.m. The post includes a formula and sample Python filters, although the relationship between the early selection time and the afternoon inflow condition is not explained clearly.

No backtest, performance statistics, or evidence of predictive value are provided. The author cautions that the method may fit low-float and high-capitalization stocks poorly, relies on limited technical conditions, and may be unsuitable for event-driven situations. The suggested improvements are to incorporate broader market conditions and use trading experience to interpret opportunities. The included code is illustrative and does not establish that its proxies faithfully measure afternoon institutional flows or the named limit-up method.

Key ideas

• The screen combines price range, ST-status exclusion, a five-session high condition, and afternoon net buying flow.
• The post presents net inflow as a way to identify stronger buying pressure.
• The stated limitations include weak coverage of company events and potential mismatch across stock types.
• No empirical results are given, and the sample flow calculations are only proxies.
