Stock Screening with Prior-Day Amplitude, Top-List Activity, and Rising KDJ

Summary

This Chinese-language stock-selection note combines three conditions: prior-day price amplitude above 1%, appearance on the prior day's trading activity list, and a rising K value in the KDJ indicator. The rationale is to pair larger price swings with signs of unusual capital activity and a short-term technical improvement. The article also sketches indicator calculations and an intersection of the resulting candidate lists, but these examples do not establish a complete trading system or specify entry, exit, or position-sizing rules.

The note identifies market reversals, the subjectivity of KDJ interpretation, and the possibility that activity-list stocks reflect influential participants as risks. It recommends combining further indicators and fundamental analysis rather than relying on one signal. No backtest performance or evidence of predictive value is reported, and the snippets contain timing and implementation details that would need to be checked before use. The method is therefore a screening idea, not a demonstrated strategy.

Key ideas

• The screen requires prior-day amplitude above 1%, prior-day top-list activity, and an increase in KDJ K.
• The proposed rationale combines volatility, unusual trading activity, and a short-term technical signal.
• The note treats KDJ interpretation and top-list activity as imperfect signals that need broader analysis.
• No measured returns or backtest evidence are provided, and implementation details require validation.
