A-Share Screening with Volatility, KDJ Crossovers, and Control Data

Summary

This note describes a Chinese A-share watchlist screen combining daily range, a newly formed KDJ bullish crossover, and a reported control indicator above a threshold. Its rationale is that a wider range signals activity, the crossover may mark improving sentiment, and the control reading may suggest buying interest. The article includes indicator formulas and a Python sketch as implementation references.

The author flags that technical signals can miss company fundamentals, KDJ can lag price, and a short-term control measure may be noisy. Suggested refinements include adding valuation and financial statement checks, other indicators, trend-aware adjustments, and refreshed control data. The note provides no backtest results or evidence that the screen predicts returns; its claims are hypotheses for further testing, and the formula examples may not implement every condition consistently.

Key ideas

• The screen requires daily amplitude above its threshold, a newly formed KDJ crossover, and a control reading above its threshold.
• It is intended to identify active stocks with a possible bullish setup.
• The author warns that KDJ may lag and that the control measure may be sensitive to individual sessions.
• Fundamental checks and additional technical signals are suggested as possible refinements.
• The document presents implementation examples but reports no performance evidence.
