Stock Screening with Price Amplitude, Control, and Chart Patterns

Summary

This Chinese-language post outlines a stock screen using price amplitude, a measure labeled today’s controlling shares, and a rounded chart shape. It discusses the general intent of combining price movement, ownership or control characteristics, and chart form. The post then proposes adding head-and-shoulders or breakout pattern conditions and mentions formula-based implementation, but provides no performance results or evidence that the screen predicts returns.

The author identifies subjective pattern recognition, computational complexity, and dependence on accurate data as limitations. The revised formula and prose are not fully aligned: the narrative proposes alternative patterns while the formula refers to multiple pattern indices. The post also recommends combining the screen with fundamental and technical measures, without specifying how to do so. Treat the criteria as an unvalidated screening concept; it gives no portfolio rules, risk controls, or backtest methodology.

Key ideas

• The proposed screen combines price amplitude, a controlling-shares measure, and chart-pattern criteria.
• The post suggests adding head-and-shoulders or breakout patterns to the selection logic.
• Pattern recognition can be subjective, computationally demanding, and sensitive to data quality.
• The document provides no backtest results or evidence of predictive performance.
