A bullish engulfing pattern is a bullish body that covers the entire body of the previous bearish candle after a decline. The next sessions decide its meaning: a higher close supports it and a close below the pattern low ends it.
What is the bullish engulfing candlestick pattern?
A bullish engulfing pattern is a two-candle reversal pattern that forms after a decline. The first candle is bearish and extends the decline. The second is bullish and its body covers the entire body of the first, so in one session buyers erase the previous session's net selling and close above where it opened. Chartists read it as a possible shift of control from sellers to buyers.
The pattern describes a change in how the stock traded, not a reason for it. It does not explain why buyers arrived, and it does not measure how far a rebound may go. Its value comes from the context around it: the decline before it, the level where it forms, the volume behind it and the sessions after it.
How to identify a bullish engulfing pattern
Check the bodies first and ignore the wicks, because the classic definition compares real bodies only. Then check the setting: the same two candles in the middle of an advance are not a reversal pattern.
- A decline comes first: lower closes over several sessions or a clear downtrend.
- Candle one is bearish: it closes below its open.
- Candle two is bullish: it closes above its open.
- Candle two opens at or below candle one's close and closes above candle one's open, so its body covers candle one's body. Stricter definitions require the second body to extend beyond the first at both ends.
- Candle one's wicks do not have to be covered. When candle two's range also exceeds candle one's high and low, the pair is an outside bar as well.
| Candle | Open ($) | Close ($) | Body ($) | Color |
|---|---|---|---|---|
| First | 52.85 | 52.00 | 0.85 | Bearish |
| Second | 51.80 | 53.40 | 1.60 | Bullish |
The second candle opens $0.20 below the first close and closes $0.55 above the first open, so its body covers the first body at both ends.
Some features add weight without changing the definition: a small first body and a large second body, a second body that also covers several earlier bodies, a long or steep decline before the pattern, and a pattern that forms at support.
Trend context: why the decline comes first
An engulfing pattern is a reversal pattern, so it needs something to reverse. Describe the decline in numbers before naming the pattern; in the figure, closes fell 8.4% over the ten sessions before the first candle. The more stretched the decline and the closer the pattern sits to a support level, the more the reversal reading has to work with.
In an uptrend, a bullish engulfing session after a short dip reads as the advance resuming rather than reversing. That is a continuation reading and deserves its own judgment: the dip's low, not a long decline, becomes the level to watch. In a sideways range, a large bullish candle often only carries price back to the middle of the range.
Check the longer trend as well. A bullish engulfing pattern below a falling 50- or 200-session moving average works against the prevailing direction, and those averages are levels where a rebound may meet selling.
Confirmation: what the next session should show
Confirmation comes after the pattern. The usual test is the next close: a close above the engulfing candle's close shows that buyers followed through. Stricter readers wait for a close above the engulfing candle's high or above a nearby resistance level, which confirms later but with more evidence.
- Confirmed: the next session closes above the engulfing close. In the figure the confirming close is $53.95 against an engulfing close of $53.40.
- Unconfirmed: the next session closes lower but stays above the pattern low. The pattern is still intact, but it has not shown follow-through.
- Invalidated: a close below the pattern low, the lower of the two candles' lows ($51.45 in the figure). The reversal reading has failed at that point.
A higher close is evidence, not a promise. Confirmed patterns also fail, and what to do with a pattern belongs to your own plan and risk limits; see stop-loss and profit targets.
Volume analysis for a bullish engulfing pattern
Volume shows how much trading stood behind the turn. A bullish engulfing session on volume well above the stock's recent average suggests that many participants took part in the reversal. The same pattern on light volume shows that little buying was needed to lift price, which says less about demand.
- Compare the engulfing session's volume with the average of the previous 10 to 20 sessions, not with a single neighboring bar. In the figure it is 2.2 times the ten-session average.
- Look at the confirming session too. Volume that stays above average on the follow-through adds weight, as in the figure at 1.3 times; a quiet follow-through is weaker.
- Heavy volume on the first, bearish candle followed by heavier volume on the engulfing candle can show selling being absorbed by buyers.
- Check the calendar. Earnings releases, index changes and options expiration days can inflate volume for reasons unrelated to the pattern.
Volume is context, not a separate verdict. A heavy-volume pattern that fails is still a failure, and a light-volume pattern can still be followed by a lasting recovery.
Failure examples and invalidation
A bullish engulfing pattern fails when sellers return and the stock closes below the pattern low. The hypothetical figure below shows a common sequence: the pattern forms on light volume during a steady decline, the next session closes lower instead of higher, and three sessions after the pattern a close below the pattern low ends the reversal reading while the decline continues.
- The decline before it lasted only a session or two, so there was little to reverse.
- The engulfing candle barely covers the first body and leaves a long upper wick, so buyers kept only part of the session's gain.
- Resistance sits just overhead, such as a falling moving average or the underside of a broken support level.
- The next session opens with a gap below the pattern low.
Write the invalidation level when you first note the pattern, before you know the outcome. In the failure example it is $52.70, the low of the engulfing candle and therefore the pattern low.
Look-alikes: piercing line, harami and outside bar
Several two-candle patterns resemble a bullish engulfing pattern. The differences lie in how far the second body reaches into the first and in whether the rule compares bodies or whole ranges.
| Pattern | Second candle | Compares |
|---|---|---|
| Bullish engulfing | Bullish body covers the whole prior bearish body | Bodies |
| Piercing line | Opens below the prior close and closes above the midpoint of the prior body, but below its open | Bodies |
| Bullish harami | Small body that sits inside the prior long bearish body | Bodies |
| Outside bar | Higher high and lower low than the prior session, either color | Ranges |
| Bearish engulfing | Bearish body covers the prior bullish body, after an advance | Bodies |
A piercing line is the near miss of an engulfing pattern. The second candle closes deep into the first body without covering it, and many chartists treat it as the less complete version until a later close above the first candle's open. A harami is the opposite shape: the second body is the smaller one, so it shows a pause in selling rather than a takeover by buyers. The candlestick patterns guide describes both.
Research checklist
Use the same steps every time so the patterns you note can be compared later. Open the stock in Stock Charts with a 3M or 6M range, where daily candles are wide enough to read, and keep the volume pane visible. TradeClever does not detect candlestick patterns, so you read the candles yourself.
- Describe the decline: how many sessions and how many percent.
- Write down the open and close of both candles and check the body rule.
- Mark the pattern low as the invalidation level.
- Compare the engulfing session's volume with its recent average.
- Mark the nearest resistance above, including the 50- and 200-session moving averages.
- Record the next close as confirmed, unconfirmed or invalidated.
- Add the stock to a watchlist to follow the outcome, and review failed patterns as carefully as confirmed ones.
