Screening Chinese Stocks by Range, Trading Volume, Gap, and Float

Summary

The document outlines a Chinese equity screening rule that combines a daily price-range threshold, current trading volume above a stated level, a higher opening price, and a cap on the number of shares in the public float. It frames these conditions as a way to find active, relatively smaller-float stocks. It also sketches an implementation using market data and a curve-shape filter based on fitting a line to closing prices and comparing average deviations with the average daily range.

The accompanying discussion cautions that the screen emphasizes short-term price action and float size while omitting company fundamentals and longer-term trends. It suggests adding technical or fundamental measures for further evaluation, but supplies no backtest, performance evidence, or validation of the proposed curve filter. The sample code’s data-field and condition choices would need careful checking before use, and the screen should be treated as an unverified idea rather than a demonstrated strategy.

Key ideas

• The proposed screen combines price range, current volume, an opening gap, and public float size.
• A curve-shape condition is approximated by fitting a line to closing prices and measuring average deviations.
• The post warns that the screen omits fundamental information and longer-term trend context.
• No backtest or performance evidence is provided, and the implementation details require independent validation.
