A-Share Reversal Screen Using Amplitude and Candlestick Patterns

Summary

This stock-selection recipe targets A-share stocks when daily high-to-low amplitude exceeds one percent, a reversal or engulfing condition is present, and a morning-star candlestick signal appears. The article describes combining the filters to seek possible price reversals and provides formula and Python examples intended to identify qualifying names.

The piece offers a screening concept, not empirical evidence: it reports no backtest, returns, benchmark comparison, or transaction costs. Its own discussion cautions that technical patterns may be affected by market volatility and speculative sentiment and do not account for company fundamentals. It suggests adding valuation measures such as price-to-earnings or price-to-book, comparing multiple indicators, and adjusting parameters over time. The examples also differ in their encoding of the reversal condition, so implementation details should be checked before using the screen. No claim is made that the resulting stocks will reverse or produce gains.

Key ideas

• The screen requires daily amplitude above one percent, a reversal pattern, and a morning-star signal.
• It combines candlestick conditions to look for potential price reversals.
• The article provides formula and Python examples but no performance evaluation.
• Fundamental information, market regime, and indicator reliability remain limitations.
