A Chinese Stock Screen Combining Turnover, Reversal, and KDJ Crossovers

Summary

This Chinese equity screening rule selects stocks with turnover between 3% and 12%, a reversal-style price pattern, and a newly formed bullish KDJ crossover. The article gives a platform query and a Python example that attempts to calculate the reversal measure, derive KDJ values from recent highs and lows, and join those results with daily turnover data. It also describes filtering for listed Shenzhen main-board stocks.

The source does not present a backtest, returns, drawdowns, or a comparison with a benchmark, so the screen’s predictive value is unestablished. It explicitly notes that the approach omits company fundamentals and that KDJ signals can be unreliable; it suggests testing additional indicators or fundamental measures. The supplied code also contains apparent inconsistencies between the stated reversal condition and the query, and references a KDJ field that is not clearly created in the calculation. Treat the implementation as illustrative and verify the definitions and data joins before using it.

Key ideas

• The screen combines a 3% to 12% turnover band, a reversal pattern, and a fresh bullish KDJ crossover.
• The example calculates KDJ from rolling nine-session highs and lows, then joins signals with turnover data.
• The proposed universe is listed stocks on the Shenzhen main board.
• The article gives no performance evidence and warns that fundamentals are omitted and KDJ may be unreliable.
• The example code and query appear inconsistent, so the signal definitions require verification.
