A-Share Screening with Daily Range, RSI, and a Two-Day High

Summary

This stock-selection idea screens for shares whose daily high-low range exceeds a threshold, whose RSI is below a ceiling, and whose current high matches the highest high over the latest two days. The accompanying explanation frames the recent high as a way to identify strength, then suggests ranking candidates by relative strength. It gives formulas and example implementation references for calculating range, RSI, and the two-day-high condition.

The document cautions that this is a simple technical screen: it does not assess company fundamentals or industry conditions, and selecting for recent price strength may perform poorly over longer horizons. It proposes adding market, policy, and fundamental information, but does not specify or test a complete combined model. No backtest, transaction costs, portfolio rules, or performance evidence are provided, so the screen should be understood as a candidate-selection heuristic rather than a validated trading strategy.

Key ideas

• The screen combines daily price range, an RSI ceiling, and a current high equal to the highest high over two days.
• The article suggests ranking qualifying shares by relative strength.
• The method focuses on recent price behavior and omits company fundamentals and industry analysis.
• The article warns that chasing recent strength may lead to weak longer-term outcomes.
• It provides indicator calculation references but no backtest or performance evidence.
