A-Share Screen Combining Volatility, Top-Trader Lists, and Technical Crossovers

Summary

This A-share stock screen combines a price-amplitude threshold, appearance on the previous day's top-trader list, and simultaneous bullish crossover signals. The examples use moving averages, MACD, and KDJ to represent the technical signals, then intersect the conditions to select stocks. The article interprets large amplitude as elevated short-term activity, top-trader-list inclusion as evidence of notable trading flows, and crossovers as signs of relative strength.

The article cautions that market reversals and inaccurate technical indicators can undermine the screen, and that simulated returns may differ from live results. It recommends incorporating additional measures such as volume, valuation, market conditions, and risk controls. No backtest results or empirical evidence are provided. The formulas and code also express some crossover conditions differently, so implementation details and timing should be checked before use. The screen is best treated as a candidate-generation method that requires independent testing and risk management.

Key ideas

• The screen requires elevated price amplitude, prior-day top-trader-list inclusion, and several technical crossover conditions.
• Moving averages, MACD, and KDJ serve as the stated technical signals.
• The article warns that reversals, imperfect indicators, and live-versus-simulated differences create risk.
• It provides no performance evidence and suggests adding market, valuation, and risk-control filters.
• The formula and code should be checked for consistent crossover definitions and timing.
