A-Share Screen Using Intraday Range, RSI, and Daily Gains

Summary

This proposed screen selects main-board stocks with a daily high-low amplitude above one percent, RSI below 65, and a daily gain above one percent. The document frames amplitude as a measure of price movement, RSI as an indicator of relative strength or overbought conditions, and the daily return as a filter for stocks rising that day. It also gives formula references for calculating these measures and sketches an additional relative-strength ranking step.

The article warns that the rule relies heavily on technical data and ignores company finances and industry conditions. It recommends considering valuation or company-quality measures and cautions that results may be sensitive to the chosen lookback and calculation method. The text does not provide a backtest, performance evidence, or a precise RSI lookback period, and its later suggestion to include other indicators changes the initial screen. The described thresholds therefore define a candidate filter, not a validated strategy.

Key ideas

• The screen requires amplitude above one percent, RSI below 65, and a daily price gain above one percent.
• The stated universe is main-board stocks.
• The article proposes relative-strength ranking as an additional selection step.
• The screen omits fundamental and industry information and may be sensitive to calculation choices.
• No test results or specified RSI lookback period are provided.
