Screening Chinese A-Shares with Range and KDJ Crossovers

Summary

This post describes a Chinese A-share screening rule that combines daily price range with a fresh KDJ crossover and excludes Beijing-listed stocks. The range filter looks for movement greater than one percent, while the KDJ condition requires the J line to cross above the D line. The post presents the rule as a way to find volatile stocks with a potentially improving short-term signal, and provides example implementations in indicator formulas and Python.

The author cautions that high range can accompany elevated risk and unstable fundamentals, and that KDJ turning points can be false signals. Suggested refinements include adding financial statement measures and other technical indicators such as MACD, RSI, or DMI. The post provides no backtest, performance statistics, or trading rules for entries, exits, and position sizing, so it describes a screening idea rather than evidence of a profitable strategy. The Beijing-stock exclusion is stated as a filter, but its rationale and implementation details are not fully substantiated.

Key ideas

• The screen combines a daily price range above one percent with a newly formed KDJ J-over-D crossover.
• It excludes Beijing-listed A-shares from the candidate pool.
• The post warns that volatile stocks may carry greater risk and KDJ signals can be misleading.
• It recommends considering fundamental data and additional indicators to refine the screen.
• No backtest or portfolio-level trading rules are provided.
