Chinese Stock Screening with Intraday Inflows and Capital Strength

Summary

This document describes a Chinese stock selection screen combining daily price amplitude, afternoon large-order net inflows, and a descending ranking by capital strength. The stated capital-strength measure relates daily net inflow to the day’s high-low range. Stocks meeting the amplitude and inflow conditions are ranked to favor those with stronger measured flows. The article also gives example indicator formulas and a Python outline for iterating over listed stocks and applying the criteria.

The approach is presented as a screening idea, not a validated trading system. The article warns that the criteria may select volatile, higher-risk shares and that short-term rankings do not establish long-term performance. It provides no performance statistics, benchmark comparison, or evidence that the screen predicts returns. The code example also contains inconsistencies and should not be treated as a complete, ready-to-run implementation. Suggested extensions include adding technical or fundamental features and diversifying holdings, but these proposals are not tested in the document.

Key ideas

• The screen combines price amplitude above a threshold with afternoon large-order net inflow.
• Qualifying stocks are ordered by a capital-strength measure based on net inflow and the daily price range.
• The article offers formula examples and a rough data-processing outline rather than a tested implementation.
• The author cautions that the screen can favor volatile, popular stocks and does not establish long-term results.
