A bullish engulfing pattern is a two-candle reversal: a small red bar followed by a larger green bar whose body completely covers the previous one. It says: yesterday's sellers are today's exhausted bystanders, and buyers just took the controls.
The pattern tells a clean story across two bars. In the first bar, sellers had control — price closed lower, bears were in charge. In the second bar, sellers tried again at the open, but buyers stepped in with enough force to reverse the move and close above where the prior bar opened. That's a complete intraday rejection of yesterday's bias.
The reason traders take engulfing patterns more seriously than single candles: it's harder to fake. A long lower wick on one candle can be liquidity-driven noise. A full body engulf takes real, sustained buying pressure across the entire bar. Bigger bodies and higher volume on the second bar are the strength signals.
Best context: a defined downtrend that's reaching a known support level (recent swing low, moving average, prior range floor) with RSI in oversold territory. The engulfing fires at the level and the bias flips — that's a tradeable setup.
Engulfing detection is straightforward — body comparison plus a directional check. The hard part is everything that comes after: is the trend actually reversing, or are we engulfing in chop? Is RSI confirming, or is this counter-momentum noise? Is there a news event about to invalidate the setup?
