Chinese Stock Screening by Intraday Range, Large-Order Flow, and Opening Gap

Summary

This article describes a Chinese equity screening approach that combines intraday price range, a large-order net-volume ranking, and the stock’s price change at the 9:25 opening auction. The intended screen seeks volatile, actively traded stocks whose early rise remains below a stated threshold. It also offers an indicator formula and a Python example, although the example substitutes turnover rate for the named large-order net-volume ranking and uses daily data fields to approximate the auction condition.

The article gives no performance results or backtest evidence. It cautions that the screen relies on short-term technical factors, omits company fundamentals, and may be too restrictive. It suggests adding other indicators and fundamental analysis, relaxing the opening-price filter, and backtesting before use. The proposed adjustments are suggestions rather than validated improvements, and the implementation details do not fully match the screening logic described in the text.

Key ideas

• The screen combines price range, large-order activity, and a limit on the 9:25 price rise.
• The article frames the setup as targeting active stocks with relatively weak early momentum.
• Its Python example uses turnover rate as a proxy, which differs from the stated large-order ranking.
• The article provides no performance evidence and recommends backtesting the rules.
• It notes that the technical screen omits long-term company fundamentals.
