A-Share Screen Using KDJ Crossovers, Volume, and Opening Gaps

Summary

This proposed A-share screen looks for stocks with a daily price range above a threshold, a newly formed KDJ crossover, current volume above a stated level, and an opening price above the prior close. The combination is meant to identify volatile shares with a short-term technical signal, active trading, and positive opening momentum. Formula and Python examples show how the author intends to calculate the conditions.

The article warns that the screen does not assess earnings prospects or business quality, and that stocks that have already risen sharply may pull back or revert. It suggests adding fundamental and valuation factors and defining exit rules. No backtest, outcome data, or comparison with alternative screens is reported. The examples also differ in how they express the crossover and calculate indicator values, so they should not be assumed to implement an identical, validated strategy.

Key ideas

• The screen combines a price-range threshold, a fresh KDJ crossover, elevated current volume, and an upward opening gap.
• The criteria are intended to capture volatility, technical momentum, trading attention, and buying interest.
• The article notes risks from weak fundamentals, price reversion, and pullbacks after prior gains.
• It offers sample formulas and code but no backtest evidence, and implementation details may differ.
