Combining Reversal Patterns, Price Range, and Bollinger Bands in a Stock Screen

Summary

This short-term stock screen combines three conditions: daily amplitude above one percent, a reversal or engulfing-style pattern, and a closing price above the Bollinger middle band but below its upper band. The article presents the combination as a way to find volatile stocks showing a reversal signal while remaining within a band-based range associated with an upward short-term trend. It includes indicator formulas and a code sketch, but gives no backtest or performance evidence to establish that the combination predicts returns.

The author notes that the method focuses on short-term price behavior and volatility, leaving fundamentals and longer-term value out of the selection process. Bollinger readings can also be affected by changing volatility and market sentiment. Proposed refinements include adding other technical and fundamental measures, adapting band parameters to market conditions, and testing the criteria more broadly. These suggestions are not evaluated in the document, and it does not specify trade exits, position sizing, or risk limits.

Key ideas

• The screen requires amplitude above one percent and a reversal-style price pattern.
• It selects stocks closing above the Bollinger middle band and below the upper band.
• The method targets short-term volatility and price behavior rather than company fundamentals.
• The article gives no performance evidence and flags sensitivity to market conditions and sentiment.
• Possible refinements include additional indicators, fundamental filters, and adapting band parameters.
