A Chinese Stock Screen Using Range, KDJ Crossovers, and Reversal Patterns

Summary

This document proposes a Chinese stock screen that requires daily price range above one percent, a three-session close-price pattern labeled as an engulfing or reversal formation, and a newly triggered KDJ crossover. It presents the combination as a way to find volatile stocks with a possible upward reversal, and supplies formula and Python examples for calculating the conditions.

The article acknowledges that reversal patterns can produce false signals, that higher volatility carries greater risk, and that the screen largely ignores company fundamentals and broader market direction. It suggests incorporating valuation or financial-statement measures, other technical indicators, and adjustments for changing market conditions. No backtest results, sample definition, or evidence of predictive performance are provided. The supplied implementations should also be checked carefully: the description of an engulfing pattern and the calculations shown may not fully match, and the code includes data-handling assumptions that require validation before use.

Key ideas

• The proposed screen combines a daily range threshold, a close-price reversal pattern, and a fresh KDJ crossover.
• The author treats elevated range as a volatility signal and the crossover as a possible improvement in sentiment.
• The article warns that the pattern may give false signals and that volatility increases risk.
• Fundamental measures and additional indicators are suggested as possible extensions.
• No backtest or evidence of trading performance is presented.
