Combining Reversal Candles, KDJ Momentum, Volume, and Valuation in a Stock Screen

Summary

This Chinese equity screening proposal combines daily amplitude above 1%, a reversal or engulfing-style candle condition, and an increase in the KDJ oscillator's K line. Its expanded version adds bullish alignment through moving-average crosses, relative volume above its recent average, and trailing price-to-earnings below 30. The document includes example formula and Python implementations, using candlestick and technical indicator calculations to construct a candidate list.

The stated rationale is to pair price movement and a reversal signal with momentum, volume confirmation, and a valuation constraint. The article warns that volatile markets can reduce signal reliability, that KDJ alone cannot describe the full market state, and that the screen omits broader fundamentals. It recommends adding other indicators and financial analysis. No backtest, measured returns, or validation of the proposed conditions is supplied; the code examples are illustrative and include platform-specific functions whose exact behavior is not explained.

Key ideas

• The initial screen looks for high amplitude, a reversal candle, and a rising KDJ K line.
• The expanded screen adds moving-average alignment, elevated relative volume, and a trailing valuation ceiling.
• The article flags sensitivity to volatile markets and the limits of relying on KDJ.
• The formulas and Python sketch are examples, with no reported performance validation.
