A-Share Momentum Screen Using Trading Range, Limit-Ups, and RSI

Summary

The document proposes a Chinese A-share stock screen that combines a daily range filter, a recent limit-up event, and an RSI-based condition intended to identify the start of a strong upward move. It gives indicator formulas and Python-style pseudocode for retrieving historical prices, calculating percentage changes, and filtering candidate stocks. The selected names are described as entering a pool for further consideration, rather than as automatic buy and sell instructions.

The rationale is that larger daily movement may accompany stronger gains, a recent limit-up may signal exceptional strength, and elevated smoothed RSI may indicate an advancing phase. The article offers no backtest results or performance evidence. It also acknowledges that technical-only selection omits fundamentals and that identifying the start of a major advance is subjective. The code and written rules differ in their lookback descriptions and implementation details, so the screen would need careful reconciliation and testing before use.

Key ideas

• The proposed screen combines daily price range, a recent limit-up event, and a smoothed RSI threshold.
• Its intended use is to identify stocks entering an early strong-advance phase for a candidate pool.
• The article provides indicator logic and sample code but no performance results.
• The author warns that technical-only screening omits fundamentals and that trend-start definitions can be subjective.
• The formulas and code contain differing lookback descriptions that require reconciliation.
