Chinese Stock Screen Using Reversal Candles and Large-Cap Value

Summary

This Chinese equity screen selects stocks with daily amplitude above 1, a reversal or engulfing-style price pattern, and circulating market capitalization above 10 billion yuan. The article describes these filters as a mix of technical conditions and a size constraint, and provides indicator-formula and Python examples. It does not report a backtest, define the pattern consistently across the examples, or demonstrate that the screen improves returns.

The author notes that a large-cap focus excludes smaller companies and that the rules do not adequately account for company financials, industry prospects, or sector differences. Suggested improvements include combining the technical signals and market-cap threshold with fundamental and industry analysis. The method is therefore best understood as a candidate-stock filter, not a complete strategy: it provides no entry or exit plan, portfolio construction method, or risk controls, and parts of the sample implementation appear inconsistent with the stated selection logic.

Key ideas

• The screen requires amplitude above 1, a reversal pattern, and circulating market capitalization above 10 billion yuan.
• The article frames the market-cap filter as a way to focus on larger stocks.
• Its indicator and Python examples do not clearly implement the same reversal definition.
• The author recommends adding company financials and industry conditions to the screen.
• No backtest or evidence of improved investment performance is provided.
