A-Share Screening with KDJ Crossovers, Moving-Average Clustering, and Opening Gaps

Summary

The document proposes screening Chinese stocks for three conditions: at least five moving averages converging, a newly formed KDJ bullish crossover, and a 9:25 a.m. gain below a stated ceiling. It interprets moving-average convergence as alignment across time horizons and the KDJ crossover as a possible shift in short-term momentum. The opening-price filter is intended to avoid stocks that have already moved sharply before the session begins.

The article cautions that technical signals can misread price action and that market sentiment and company results also matter. It suggests adding other indicators and broader market factors. However, the included Python example does not calculate the claimed moving-average or KDJ conditions; it mostly checks whether codes occur in data and filters on a historical percentage-change field. No test results are reported, so neither the proposed screen nor the sample implementation demonstrates an investment edge.

Key ideas

• The proposed screen combines moving-average convergence, a fresh KDJ bullish crossover, and a limited pre-open gain.
• The article treats convergence as alignment across short- and medium-term price trends.
• It warns that technical indicators can produce false signals and recommends considering market and company factors.
• The sample code does not implement the stated indicator conditions, and no performance evidence is supplied.
