Stock Screen Using Daily Range, the 10-Day Average, and Recent Limit-Ups

Summary

The document describes a stock screen combining three conditions: daily price amplitude above 1%, an opening price within 5% of the 10-day moving average, and at least one limit-up event in the prior 25 days. It frames these as signals for elevated activity, proximity to a short-term average, and recent market attention. Reference formulas are provided for both a charting platform and Python, including rolling calculations and a prior-period shift for the limit-up condition.

The article suggests adding other technical indicators and fundamental data, and using stop-losses and position controls. It gives no backtest, performance results, transaction rules, or detailed definition of how limit-ups should be identified across different securities. The sample implementations also differ in how they calculate amplitude and identify limit-up events, so the screen would need careful validation before use. The stated selection conditions are a starting point rather than evidence that the chosen stocks will deliver gains.

Key ideas

• The screen selects stocks with daily amplitude above 1%.\nIt requires the opening price to lie within 5% of the 10-day moving average.\nIt also requires a limit-up event within the preceding 25 days.\nThe article recommends supplementing these filters with other indicators, fundamentals, and risk controls.\nNo empirical performance evidence is provided.
