A-Share Screening with KDJ Crossovers, Daily Range, and Opening Gap Limits

Summary

This A-share screening idea combines a daily trading-range filter, a newly formed KDJ crossover, and a cap on the pre-open price gain. The stated rationale is to find volatile stocks whose short-term momentum may be improving while avoiding candidates that have already gapped up sharply. The post describes putting qualifying shares into a watch or investment pool rather than specifying entry, exit, or position-sizing rules.

The article includes indicator and Python examples, but the details are not fully consistent: its prose says the 9:25 gain should be below 6%, while the displayed formula and code appear to test a different condition or use later daily prices as a proxy. It gives no backtest results or measured evidence that the filters predict returns. The author notes that the screen may return few stocks and ignores company fundamentals, and suggests adding financial and other technical factors.

Key ideas

• The screen combines a daily range above 1% with a newly formed KDJ crossover.
• It aims to limit candidates whose pre-open gain is already large.
• The proposed rationale is that range signals volatility while a crossover may indicate improving momentum.
• The article provides example formulas but does not establish consistent 9:25 timing logic across them.
• The method omits fundamentals and provides no performance test or trading exit rules.
