Chinese Stock Screen Using Intraday Range, Afternoon Flow, and Two-Day Highs

Summary

This stock-selection rule combines three conditions: daily price amplitude above a threshold, a positive afternoon large-order flow proxy, and a high that exceeds the highs of the preceding two sessions. The post frames the combination as a way to identify strong price action while using afternoon buying activity as confirmation. It supplies formula references for the range and two-day high conditions, along with sample Python-style logic intended to scan listed Chinese stocks.

The article cautions that a two-day high comparison can omit relevant historical context and suggests combining the screen with technical or fundamental measures and repeated testing. It provides no backtest statistics or evidence of returns, and the code reference has apparent inconsistencies, including mismatched variable names and expressions that may not run as written. The flow condition is presented as a proxy rather than a demonstrated measure of buyer dominance, so the screen should be treated as a candidate filter requiring validation.

Key ideas

• The screen selects stocks with price amplitude above a threshold, afternoon flow strength, and a two-day high.
• The stated purpose is to flag strong price action and reduce profit giveback risk.
• The post recommends combining the conditions with other technical or fundamental measures.
• No performance evidence is provided, and the sample implementation contains inconsistencies.
