A Chinese Stock Screen Using Turnover, Large-Order Flow, and Weekly Strength

Summary

This Chinese stock-screening example selects shares with turnover between 3% and 12%, a positive product of price change and net large-order volume, and a bullish weekly candle. The article frames the weekly condition as an addition intended to favor stocks showing upward movement. It also provides example formula and Python implementations, with the Python version adding filters such as price, float size, unusual volume, and a ranking based on turnover and volume. These implementations do not match exactly, so they should be checked against the stated screening rule before use.

The article reports no backtest or performance evidence. It warns that the screen omits fundamental and industry factors, may select weak candidates, and can capture temporary rebounds. It suggests combining the technical filters with valuation measures or indicators such as RSI and MACD, but does not test those additions. The criteria are therefore a simple screening hypothesis, not a validated investment strategy; market regime, data definitions, and execution costs may materially affect results.

Key ideas

• The core screen combines a turnover range with positive price-change and large-order-flow product, plus a bullish weekly candle.
• The accompanying Python example adds filters that are not all part of the stated core rule.
• The article supplies no performance results to establish whether the screen has predictive value.
• The author notes that the screen omits fundamental and industry information and may select temporary rebounds.
• Additional valuation or technical indicators are suggested, but their effects are not evaluated.
