Engulfing Candlesticks

An engulfing pattern is a two-candle formation. The key comparison is between the real bodies of the two candles — the distance between each candle's open and close — not the wicks (the thin lines showing the high and low).

The pattern forms when the second candle's real body completely covers, or 'engulfs', the first candle's real body. In other words, the second candle opens beyond one end of the first body and closes beyond the other end, so the first body sits entirely within the range of the second.

There are two versions, defined by direction:

• Bullish engulfing: a smaller down-candle (close below open) is followed by a larger up-candle (close above open) whose body engulfs it.
• Bearish engulfing: a smaller up-candle is followed by a larger down-candle whose body engulfs it.

A common point of confusion is the role of wicks. The strict definition looks at bodies only; the second candle's wicks may or may not extend past the first candle's wicks. Some traders apply a looser definition that also considers the full high-to-low range, so it helps to be clear about which definition you are using when you read or build a tool.

Traders typically look for a bullish engulfing using a checklist like this:

1. First candle: a down-candle (close below its open), often with a relatively small body.
2. Second candle: an up-candle (close above its open) whose body opens at or below the first candle's close and closes at or above the first candle's open — so the up-body covers the down-body.
3. Context: it appears after a visible move lower, rather than in the middle of a flat range.

The second candle being noticeably larger than the first is often treated as a sign that buyers were more active than sellers over that period. Traders often describe this as a possible shift from selling pressure toward buying pressure.

It is worth stating plainly: identifying the shape does not tell you what happens next. The pattern describes what already occurred over two candles. Whether price continues higher, stalls, or reverses is unknown, and the same shape can appear before moves in either direction.

The bearish engulfing is the mirror image:

1. First candle: an up-candle (close above its open), often with a relatively small body.
2. Second candle: a down-candle (close below its open) whose body opens at or above the first candle's close and closes at or below the first candle's open — so the down-body covers the up-body.
3. Context: it appears after a visible move higher.

Traders often read this as a period where sellers became more active than buyers, and may interpret it as a possible pause or shift in upward momentum. As with the bullish version, this is an interpretation of recent price action, not a forecast. A bearish engulfing can be followed by a continued move higher just as easily as by a move lower; the shape alone carries no guarantee.

Most traders treat an engulfing pattern as one input among several rather than a stand-alone signal. Common context factors include:

• Location: a pattern that forms near a level many traders watch — such as a prior support or resistance area — is often given more attention than one in the middle of nowhere.
• Prior trend: these patterns are usually discussed as 'reversal-type' shapes, so traders often look for them after a clear preceding move rather than inside a sideways chop, where they tend to be far less meaningful.
• Relative size: a second body that dwarfs the first is read differently from one that barely covers it.
• Volume: some traders note whether the engulfing candle formed on higher activity, treating that as supporting (not confirming) information.
• Timeframe: a pattern on a daily chart represents a full day of behaviour; the same shape on a 1-minute chart represents one minute and is typically considered far noisier.

None of these turn the pattern into a prediction. They are simply ways traders try to judge whether a given pattern is worth their attention. Patterns fail regularly, and a disciplined approach treats every setup as a hypothesis that may be wrong.

The snippet below is an educational example that detects the strict, body-only definition of bullish and bearish engulfing and marks them on the chart. It is for illustration of how detection works — it does not generate buy/sell signals and makes no claim about what price will do next.

//@version=6
indicator("Engulfing Marker (Educational)", overlay = true)

// Real-body boundaries of current and previous candle
bodyHigh = math.max(open, close)
bodyLow  = math.min(open, close)
prevBodyHigh = math.max(open[1], close[1])
prevBodyLow  = math.min(open[1], close[1])

prevDown = close[1] < open[1]
prevUp   = close[1] > open[1]
curUp    = close > open
curDown  = close < open

// Current body fully covers previous body
engulfsPrev = bodyHigh >= prevBodyHigh and bodyLow <= prevBodyLow

bullishEngulf = prevDown and curUp and engulfsPrev
bearishEngulf = prevUp and curDown and engulfsPrev

plotshape(bullishEngulf, title = "Bullish Engulfing", style = shape.triangleup,
     location = location.belowbar, color = color.teal, size = size.small)
plotshape(bearishEngulf, title = "Bearish Engulfing", style = shape.triangledown,
     location = location.abovebar, color = color.red, size = size.small)

A marker appearing on your chart only means the shape was present on those two candles. It is not an instruction to do anything. Past patterns do not predict future prices, and trading carries a real risk of loss — treat any tool like this as a study aid, not a decision-maker.
