Stock Screening with Intraday Range, Low K-Line Value, and Turnover

Summary

The document proposes a stock screen using three conditions: daily high-to-low amplitude above 1%, a K-line-related value below 20, and prior-day turnover above 8%. It frames amplitude as a volatility filter, the K-line threshold as a low-position condition, and turnover as a measure of trading activity. It also gives sample implementations for a charting platform and Python, though the precise definition of the K-line field is not explained consistently.

The post offers no backtest, performance statistics, or market sample, so it does not establish whether the screen predicts returns. Its own caveats are that it omits company fundamentals and can be affected by market conditions or speculative activity. It suggests combining technical, fundamental, industry, and liquidity information, while noting that additional model complexity and interpretability should be considered.

Key ideas

• The screen requires amplitude above 1%, a K-line value below 20, and prior-day turnover above 8%.
• The post interprets amplitude as a volatility filter and turnover as a participation measure.
• The K-line variable is not clearly defined in the document.
• The screen is presented without backtest evidence or return statistics.
• The author recommends adding fundamental and market context and managing model complexity.
