Candlestick Patterns

Bullish & Bearish Engulfing Reversal

A candle's real body completely swallows the one before it, and the trade is betting that flip in control keeps going.

Watch the tape print, then call it

Real OHLC candles reveal one at a time. Whenever a new bar completes, decide whether the last two bars form a genuine engulfing signal and click Call It. The page then runs the actual body-containment test on the real open, high, low, and close of both bars, not on how the shapes look.

How it works

  1. The body has to fully contain the prior body. A bullish engulf needs the prior candle to close red (close below open), the new candle to close green, the new candle's open at or below the prior candle's close, and the new candle's close at or above the prior candle's open. A bearish engulf is the same test flipped at a high: prior candle green, new candle red, new open at or above the prior close, new close at or below the prior open.
  2. Wicks do not count. The rule only checks the two real bodies (open to close). A candle can have a long wick that pokes past the prior high or low and still fail the engulf test if the body itself does not fully cover the prior body, and the reverse is also true.
  3. Same-color pairs never qualify. Two green candles or two red candles in a row cannot form an engulfing pattern no matter how much bigger the second body is, since the pattern is defined by a color flip plus full containment, not by size alone.
  4. Location changes what the signal is worth. The same mechanically valid engulf can print at a clear swing extreme, where it marks a real change in who is in control, or in the middle of an established trend, where it is more often just noise inside the existing move. The tape mixes both.
  5. The detector tally is the same test, run automatically. Every pair of bars gets checked the instant the second one completes. Comparing your called signals against the detector's running count shows where your eye agrees with the math and where it does not.

Where this breaks

A valid engulf with no trend behind it is still just two candles

The body-containment test has no idea what came before it. A mechanically perfect bullish engulf can print in the middle of a flat, directionless chop with no prior decline to reverse, and it passes the test exactly the same as one that prints at the bottom of a clean five-bar slide. The math cannot tell the difference between a genuine change in control and a random two-candle coincidence sitting in the noise. That is why the tape includes a weaker, mid-trend engulf alongside the ones at swing extremes: the rule passes both, but only one of them has real context behind it.
