Chinese Stock Screen Using Intraday Inflows, Volatility, and a Long-Term Average

Summary

This Chinese A-share screening idea combines a daily price-range threshold, afternoon large-order net inflow, and a condition that yesterday’s price is above the 250-day moving average. It proposes selecting the qualifying stock with the strongest gain. The document presents the range as a short-term activity measure, the order-flow condition as a capital-flow signal, and the long moving average as a longer-term trend filter. It includes example indicator formulas and a Python sketch, but does not report backtest results or measured performance.

The author notes that the screen emphasizes short-term movement and long-term direction while omitting fuller analysis of company fundamentals and longer-run prospects. Selecting the strongest recent gainer may expose the portfolio to reversals. The examples also do not clearly implement the stated ranking method: the Python sketch applies conditions across historical data and its score handling does not establish a meaningful gain ranking. The proposed refinements include adding valuation measures and filters such as market capitalization or industry, so the screen should be treated as an outline rather than a validated strategy.

Key ideas

• The screen combines a minimum daily price range, afternoon large-order inflow, and price strength relative to a 250-day average.
• It proposes choosing the strongest gainer among stocks that pass the filters.
• The article provides formula and Python examples but no performance evidence.
• The approach omits broader fundamental analysis and may select stocks vulnerable to pullbacks.
• The supplied code does not clearly implement the stated ranking procedure.
