Short-Term Stock Screen Using Range, Volume, Control, and Gap-Up Signals

Summary

This proposed short-term screen selects stocks with a large daily range, an indicator described as prior-day main-force control, current trading volume above a stated level, and an opening price above the previous close. The article associates these conditions with volatility, capital flows, attention, and market enthusiasm. It offers indicator shorthand and a Python-style example, but the code uses proxies such as turnover ratio and comparisons with prior closes, which may not match the prose definitions directly.

The document provides no backtest or return evidence. It warns that combining several filters may leave very few candidates and that short-term trading carries elevated risk, calling for position and risk controls. It also recommends considering company fundamentals, technical context, and valuation. The screen is best understood as an illustrative selection rule: the meanings and timing of its variables need to be clarified, and the signal would need testing across market conditions before being relied upon.

Key ideas

• The proposed screen combines a large price range, a control indicator, high current volume, and a gap-up open.
• The article links these conditions to volatility, capital flows, trading attention, and market heat.
• Its code example may use proxies that differ from the written signal descriptions.
• No performance evidence is provided, and the post flags sparse selections and short-term risk.
• The author recommends broader company analysis and risk controls.
