Stock Screening by Price Range, Turnover, and the Ten-Day Average

Summary

This stock screen selects shares whose daily high-low range exceeds one, whose prior-day actual turnover is between 3% and 28%, and whose opening price is near the ten-day moving average. The article frames the range and turnover filters as ways to focus on active stocks, while the moving-average condition is intended to keep the open near a recent price reference. It includes sample indicator and Python implementations of the three conditions.

No backtest, returns, or evidence that these filters improve selection is supplied. The article cautions that it omits company fundamentals and that a fixed ten-day average may not suit different stocks or market conditions. The examples also appear to use inconsistent definitions for amplitude, prior-day turnover, and the moving-average input, so the exact screening logic needs careful verification before implementation or evaluation.

Key ideas

• The screen combines a daily price-range threshold, a prior-day turnover band, and an opening price near the ten-day moving average.
• The proposed rationale is to favor active stocks whose opening price remains near a recent trend reference.
• Example implementations are included, but the document reports no backtest or performance evidence.
• The screen omits fundamental factors and may not fit the behavior of all stocks.
• The sample formulas use potentially inconsistent data definitions that require verification.
