A Chinese Stock Screen Using Volatility, Volume, Opening Price, and a Reversal Signal

Summary

This post describes a Chinese equity screening rule that combines price amplitude above 1, current trading volume above 10,000 lots, a higher open, and a named morning-star signal. The rationale is that larger price movement may indicate short-term opportunity, volume may indicate liquidity, and the reversal pattern may suggest a possible turning point. It includes example indicator logic and a Python workflow for applying the filters to listed stocks.

The post cautions that the screen omits company fundamentals and capital flows, may follow market noise, and can mistake a temporary price fluctuation for a genuine reversal. It recommends combining the signal with other technical measures, industry context, and financial information. The material offers a rule and implementation sketch, but no backtest, performance results, or validation of the indicator; its assertions about the signals should therefore be treated as hypotheses rather than demonstrated effects.

Key ideas

• The screen combines price amplitude, current volume, a higher open, and a morning-star reversal pattern.
• The post treats volume as a rough liquidity filter and the reversal pattern as a possible entry signal.
• The author warns that the rule excludes fundamentals and capital-flow information.
• No performance evidence is presented, and the reversal signal may reflect only a short-lived move.
