Bullish reversal pattern
Bullish Engulfing Pattern: Rules, Psychology and Entries
A two-candle reversal that carries its own confirmation. When a green candle completely engulfs the prior red one, control of the market changed hands in a single session.

A bullish engulfing pattern is two candles: a red one, then a green one whose real body completely covers it. In a single session, sellers lost every point they had gained the day before.
That is a different message from a hammer. A hammer says buyers defended a low. An engulfing candle says buyers took back an entire session. The pattern comes with its own confirmation built in, which is why it sits near the top of most traders’ reversal lists.
The identification rules
Four conditions, and all four must hold.
- A clear downtrend or pullback precedes it. Without a decline there is nothing to reverse, and an “engulfing” candle inside a range is just a volatile session.
- The first candle is red, closing below its open. A doji first candle does not qualify, because there is no body to engulf.
- The second candle is green, closing above its open.
- The second body completely engulfs the first body. Its open is at or below the first candle’s close, and its close is at or above the first candle’s open.
Only the real bodies matter. Shadows are ignored in the classical definition. If the shadows are engulfed as well, you have an outside bar, which is stronger, though it is a bonus rather than a requirement.
What makes one stronger than another
Not all valid engulfing patterns are equal. These factors separate the ones worth trading:
| Factor | Stronger | Weaker |
|---|---|---|
| Size of the engulfing body | Covers 2–3 prior candles | Covers the prior body by a fraction |
| Volume on day 2 | Well above the recent average | At or below average |
| First candle | Small-bodied, showing seller exhaustion | Large-bodied, showing seller strength |
| Location | At a marked support level or prior swing low | Mid-range, nothing beneath it |
| Close position | Near the high of the candle | In the middle of the candle |
An engulfing candle that closes in the middle of its own range is telling you sellers fought back late in the session. The pattern is valid and the conviction is not.
Why it works
Think about who is on each side of that second candle.
The session opens at or below the previous close. Everyone holding short is comfortable and the downtrend appears intact. Then buyers arrive with enough size to run price through the entire prior session’s range and close above where sellers had opened the day before.
By the close, every short position opened during the previous session is underwater. Every stop-loss order sitting above the prior candle’s open has been triggered. Short covering adds buying pressure on top of the original demand, which is why engulfing candles often produce immediate follow-through rather than a slow grind.
The volume tells you which story you are in. Heavy volume means real institutional size changed hands. Light volume means the market drifted up through a thin order book, and the move is far easier to reverse.
How to trade it
Entry
You have two reasonable options, and they trade win rate against reward.
The first is entering on the close of the engulfing candle. You get in while momentum is live, and this is what the pattern is designed for. The second is entering on a pullback to the midpoint of the engulfing candle’s range. Better price, tighter stop, larger position, with the cost that a meaningful share of strong engulfing candles never pull back at all, and you miss those entirely.
If you take the pullback entry, decide in advance how many sessions you will wait before cancelling the order. Two or three is typical. An engulfing pattern that has gone sideways for a week has lost its momentum.
Stop loss
Below the low of the engulfing candle. Traders sometimes put it below the low of the first candle instead, or at some arbitrary percentage; both ignore what the pattern told you.
The logic is the same as with any candle-based stop. The engulfing candle’s low is where the buyers who created the pattern first stepped in. A close beneath it means they have been overwhelmed and the premise is void.
Target
Measure risk from entry to stop, then work in multiples of it. The practical checkpoints are the first resistance, meaning the swing high that started the decline, and then 2R and 3R, where you take partial profits so a reversal does not turn a winner into a scratch.
Run the numbers through the risk/reward calculator before you enter. If the nearest resistance sits closer than 1.5R, the setup is not worth the risk regardless of how clean the candle looks.
Common mistakes
- Trading it in a range. Engulfing candles appear constantly in choppy markets and mean nothing there. The pattern needs a trend to reverse.
- Ignoring volume. A bullish engulfing candle on below-average volume is just drift.
- Comparing wicks instead of bodies. The rule is body engulfs body. Traders who measure high to low find “patterns” everywhere and wonder why their results are random.
- Taking every one. In a strong downtrend you will see several. The ones that work tend to be at levels you had already marked as significant before the candle printed.
Bullish vs. bearish engulfing
The bearish version is the exact mirror: a green candle followed by a red candle whose body engulfs it, appearing after an uptrend. Everything in this guide applies with the signs flipped, including the stop, which sits above the engulfing candle’s high.
If you can read one, you can read the other. Continue with the bearish engulfing pattern, or compare this against the hammer to see how a two-candle signal differs from a single-candle one.
Frequently asked questions
Do the shadows need to be engulfed too?
No. The classical definition requires only that the second candle's real body (open to close) completely covers the first candle's real body. If the shadows are also engulfed, the pattern is stronger and is sometimes called an outside bar, but it is not required.
How much bigger should the second candle be?
It must fully cover the first body, and the more it exceeds it the better. A green candle that engulfs the prior body by a hair is technically valid but weak. One that engulfs two or three prior candles represents a genuine shift in supply and demand.
Does a bullish engulfing pattern need a gap down to open?
The strictest classical definition requires the second candle to open below the first candle's close, which in stock markets often means a gap down. In 24-hour markets like forex and crypto, gaps are rare and the pattern is usually accepted when the second candle simply opens at or near the prior close.
What invalidates the pattern after it forms?
A close below the low of the engulfing candle. That low is the point at which buyers who stepped in are collectively underwater, and it is the natural stop level for the trade.
Is a bullish engulfing pattern better than a hammer?
Generally yes, because the confirmation is built into the pattern itself. A hammer needs a following candle to close above its high before you act. A bullish engulfing candle has already closed above the prior session's open, so the demand has already proved itself. The trade-off is that the entry price is worse.
