Short-Term A-Share Screen Using Range, Volume, and Opening Price

Summary

This note outlines a short-term stock screen that combines a daily price-movement threshold, current volume above a stated level, a higher opening price, and exclusion of stocks that closed at the daily limit the prior day. It frames range and volume as signs of activity, and a higher open as a possible bullish signal. Formula and Python examples are included as implementation references.

The author cautions that the screen focuses on near-term price action and may overlook fundamentals and broader market conditions. Its restrictive filters could also exclude potential opportunities. Suggested additions include valuation and market capitalization measures, other technical indicators, market direction, industry rotation, and macroeconomic context. The document offers no backtest or measured evidence for the claimed potential, and the examples contain differences in how conditions are expressed, so they warrant careful review before use.

Key ideas

• The proposed screen combines price range, current trading volume, a higher open, and exclusion of prior-day limit-up stocks.
• The approach is framed as a short-term activity and price-action filter.
• The author warns that it omits fundamentals and broader market influences.
• Potential refinements include valuation, market trend, industry rotation, and macroeconomic data.
• The document provides code examples but no performance evaluation.
