Screening Stocks by Range, Reversal Candles, and Control Measure

Summary

This stock selection proposal combines a daily amplitude threshold, a recent reversal candle pattern, and a measure described as today’s control rate. Its refined rule requires amplitude above one percent, a reversal pattern within the past three days, and a control rate above 21 percent. The document supplies example indicator and Python-style implementations, though the snippets use differing definitions for amplitude, the reversal condition, and the control measure.

The accompanying discussion characterizes the screen as a way to find volatile stocks with a possible reversal setup. It cautions that a short-term control measure cannot establish a company’s real value or forecast future prices, and suggests adding other technical and fundamental inputs. No backtest, sample, or return evidence is provided, so the proposed filters should be treated as a screening hypothesis rather than a demonstrated strategy.

Key ideas

• The screen combines amplitude above one percent, a recent reversal pattern, and a control measure above 21 percent.
• The refined rule looks for a reversal within the past three days.
• The example implementations do not use fully consistent definitions for all filters.
• The post recommends broader analysis and notes that the screen does not predict future performance.
