A Chinese Stock Screen Combining Rising Lows, Volatility, and Auction Flows

Summary

This proposed Chinese equity screen combines daily amplitude above a threshold, progressively higher bottoms, and signs of large or very large buying during the opening auction. It also describes an additional large-order volume condition and suggests combining technical, sentiment, and fundamental measures. The article frames these filters as a way to identify short-term price strength and institutional buying activity.

The supporting evidence is a qualitative rationale and example indicator logic, not reported performance results. The implementation examples do not consistently match the stated strategy: the Python sample uses high-price standard deviation and up-day volume calculations, while the written logic emphasizes auction flows. The post warns that short-term flow signals can overlook company fundamentals, depend on parameter and data quality, and should be assessed alongside other indicators. It offers no backtest evidence to establish predictive value.

Key ideas

• The screen seeks stocks with amplitude above one and a sequence of rising lows.
• It uses opening-auction price movement and large-order buying as flow signals.
• The article recommends adding technical, sentiment, and fundamental measures for context.
• Its examples do not fully align with the stated auction-based screening rules.
• No performance results are provided, and data quality and short-term signal risks remain.
