A Short-Term Stock Screen Using Range, RSI, and Prior Lows

Summary

This Chinese-language article describes an equity screen requiring daily amplitude above 1, RSI below 65, and a closing price above a prior low. The intended rationale is to find shares with notable movement that are not considered overbought, while using the prior-low comparison as a short-term price condition. It also suggests adding trend measures such as moving averages or MACD and considering company fundamentals.

The article provides indicator formula references and illustrative Python-like selection logic, including a relative-strength ranking step. It reports no backtest, sample, transaction costs, or live results, so the proposed filters should be treated as an unvalidated screening idea. The text also leaves some implementation details dependent on the chosen lookback period and platform conventions, and acknowledges that short-term price behavior can be unstable and may miss longer-term trends.

Key ideas

• The screen combines an amplitude threshold, an RSI ceiling, and a close-above-prior-low condition.
• The rationale is to select actively moving stocks without selecting those deemed overbought by RSI.
• The article proposes adding trend and fundamental information as further filters.
• An example ranking step sorts selected stocks by relative strength.
• No empirical performance evidence is supplied, and short-term signals may be unstable.
