Combining Intraday Range, Engulfing Reversals, and Rounded Patterns for Stock Selection

Summary

This Chinese-language note proposes a stock screen combining a daily high-low range above 1%, a recent engulfing reversal, and a rounded price pattern. It suggests using the patterns as supporting filters alongside positive recent returns, analyst recommendations, and industry trends. The note also offers indicator-formula and Python examples, though the Python example uses candlestick pattern functions whose names do not clearly match the described patterns.

The author argues that combining two shapes may reduce sensitivity to popular stocks, but warns that the pattern constraints narrow the candidate pool and can concentrate selections. Pattern-based signals may lag, underperform the market, and depend heavily on subjective interpretation. The text supplies no backtest results or evidence that the screen outperforms a benchmark; its claims about potential improvement are suggestions rather than demonstrated findings. It recommends objective pattern definitions and fundamental indicators to complement the technical filters.

Key ideas

• The proposed screen combines a range filter with recent engulfing and rounded price patterns.
• The note recommends supplementing chart patterns with positive returns and fundamental or industry information.
• Restrictive pattern conditions can reduce the candidate universe and concentrate holdings.
• Pattern signals may lag and depend on subjective interpretation, so the rules need objective definitions.
• The document provides example formulas but no performance test supporting the strategy.
