Screening Chinese Stocks for Reversal Bars, Gains, and Large-Order Flows

Summary

This note proposes screening main-board Chinese stocks using a turnover range of 3% to 12%, a reversal-style pattern, a daily gain above 2%, and a large-order volume condition. The accompanying formula compares recent and longer-term volume averages as a proxy for unusually strong trading activity, while the discussion interprets the combination as seeking stocks with price strength and buying interest. Sample data code also attempts to compare large-order buying and selling and sort the resulting list by market value.

The author notes that the screen does not adequately assess company fundamentals or policy conditions, so selected shares may be low quality or risky. Suggested refinements include valuation, sector flows, and positioning data. No backtest or performance evidence is provided. The formula, narrative, and sample code do not map cleanly to one another: in particular, the volume ratio is labeled as a large-order net-volume measure, while the sample data steps mix equity screening with futures fields. The implementation therefore needs careful validation before use.

Key ideas

• The proposed screen combines turnover between 3% and 12%, a reversal pattern, and a daily rise above 2%.
• A volume comparison against shorter and longer averages is used as a proxy for unusual buying activity.
• The sample code also seeks evidence that large-order buying exceeds selling.
• The article warns that the method omits detailed fundamental and policy analysis.
• No performance results are provided, and the formula and sample code have implementation inconsistencies.
