Stock Screening with Daily Range, Reversal Candles, and Bid-Side Volume

Summary

This stock screen combines three conditions: a daily high-low range above one percent, a reversal or engulfing-style candle signal, and first-level buy volume greater than sell volume. The article frames the range as a volatility filter and the volume comparison as an indication of relative buying and selling pressure. It provides example formulas and a Python-style implementation, but gives no backtest, measured results, or evidence that these conditions predict returns.

The source warns that the rules rely only on technical and volume information, omit company fundamentals, and may misclassify stocks when based on a limited observation period. It suggests incorporating valuation measures or machine-learning methods, though it does not specify how to do so or provide validation. The reversal condition is not defined consistently across the examples, making the intended candle pattern and implementation worth checking before use. The rules are best understood as a screening idea requiring precise definitions and testing.

Key ideas

• The screen requires a daily high-low range greater than one percent.
• It adds a reversal-style candle condition, though the examples do not define it consistently.
• First-level buy volume must exceed sell volume.
• The article identifies its limited use of technical and volume data as a weakness.
• No backtest or predictive evidence is presented.
