Screening Chinese Stocks by Volatility, MACD Contraction, and Dragon-Tiger List Activity

Summary

The document proposes a Chinese equity screen that combines daily price amplitude above 1, a shrinking negative MACD histogram on a 15-minute chart, and appearance on the previous day’s Dragon-Tiger List, a market activity listing. It frames amplitude as a way to find volatile stocks, MACD contraction as a possible sign of changing direction, and the listing as a sign of heightened attention. It also sketches formula and Python-based implementations using market data and technical indicator tools.

The author cautions that listed stocks may see buying interest fade, and that highly volatile, smaller-cap names may include recent listings or weak businesses. Suggested refinements include adding valuation, dividend, chart-pattern, moving-average, and growth criteria. The material provides no backtest, performance statistics, or precise validation of its signals; the example code and data-field choices should therefore be checked before use.

Key ideas

• The proposed screen combines price amplitude, a contracting negative MACD histogram, and recent Dragon-Tiger List appearance.
• The MACD condition uses 15-minute data to identify a negative histogram that is becoming less negative.
• The listing criterion is intended to capture stocks receiving elevated market attention.
• The document warns that attention can dissipate and high-amplitude stocks may carry business-quality risks.
• It suggests adding fundamental and technical filters, but reports no measured results.
