Screening Stocks for Recent Gains and a Lower Daily Low

Summary

This A-share screening proposal looks for stocks with a daily range above 1%, a positive but limited 10-day gain, and a current session low below the prior session’s low. The post interprets the range and return filters as signs of recent strength, while the lower low may identify a pullback that offers a cheaper entry. It provides example indicator logic and a data-fetching script, but does not report a backtest or measured results.

The author notes that the rules omit trading volume, company fundamentals, and longer-term value, and that short-term price movement can be sensitive to market sentiment. Suggested additions include volume, market capitalization, and fundamental data, along with a decision about intended holding horizon, portfolio construction, stop-loss rules, and risk controls. The written conditions and code are not fully consistent in every detail, so they should be checked before implementation. The proposal is best treated as a basic screening hypothesis, not evidence of an effective trading strategy.

Key ideas

• The screen combines a daily range threshold, a bounded 10-day gain, and a lower current-day low.
• The post treats a lower low as a possible pullback entry after recent strength.
• Volume, fundamentals, and longer-term value are absent from the core conditions.
• The author recommends adding company and market information and setting risk controls.
• No backtest results are supplied, and the example code should be checked against the stated rules.
