Stock Screening with Price Amplitude, Low K Value, and Large-Order Flow

Summary

This note describes a Chinese equity screen combining daily price amplitude above 1%, a K indicator below 20, and a high ranking for net large-order volume. It presents the conditions as a way to combine price movement, a potentially low technical reading, and buying activity. The examples refer to ranking stocks by volume, with a top-50 cutoff, and give sample implementations for screening and sorting candidates.

The note cautions that the screen omits company fundamentals and financial condition, and that large-order rankings can be affected by market conditions and data update delays. It suggests adding other technical patterns, fundamental and industry information, and additional capital-flow measures. No backtest results or performance evidence are provided, and the example code’s volume ranking is only a proxy for the described large-order net-volume measure.

Key ideas

• The screen combines amplitude above 1%, a K reading below 20, and a high large-order net-volume ranking.
• The examples use a top-50 volume ranking as a screening cutoff.
• The note warns that the method omits fundamentals and may rely on delayed or market-sensitive flow data.
• It proposes adding technical, fundamental, industry, and capital-flow factors.
