Engulfing and Harami are both two-candle reversal patterns in candlestick charting, but they signal conviction in opposite ways. An engulfing pattern occurs when a second candle's body completely swallows the first candle's body, signaling strong, decisive reversal pressure. A harami is essentially the inverse structure — a smaller second candle contained entirely within the first candle's range, signaling hesitation rather than force.
Traders compare them because the strength of the signal differs meaningfully: engulfing patterns tend to mark a clear shift in control between buyers and sellers, while harami patterns flag indecision that may or may not develop into a full reversal.
