Engulfing candle: what it is worth

The definition, and the detail about shadows

A bullish engulfing is made of two candles, in a downward price trend. The first has a bearish body. The second has a larger bullish body, which closes above the first candle's open and opens below its close.

The second body therefore fully engulfs the first. And here is the detail almost every presentation misses: you ignore the shadows. The comparison is on bodies, only. A candle whose body engulfs the previous body is an engulfing candle, even if its shadow does not exceed yesterday's.

That difference matters in a study. If you also require the second candle to engulf the extremes, you are counting a different and much rarer pattern, and your numbers will not compare to any publication.

The bearish engulfing is the exact mirror: two candles in an upward trend, the second with a bearish body engulfing the first candle's bullish body.

What the pattern tells you

The reading is intuitive and that explains its popularity. One period ended in one direction, the next erased that entire body and went further. The side that was leading lost in one period the ground it had gained in the previous one.

It is therefore a takeover, and it is visible to the naked eye, without measuring. That is both its strength and its weakness: a pattern spotted without effort is spotted by everybody at the same time.

One reading remark worth the trouble. Merge the two candles mentally into one, taking the first candle's open, the second candle's close and the extremes of both. You almost always get a candle with a clean body in the new direction. The engulfing says nothing more than that single candle, and you would read it as such on the timeframe above.

The numbers, and why they disappoint

Measurements published by Thomas Bulkowski for the bullish engulfing, quoted as they stand.

Theoretical performance: bullish reversal. Tested performance: bullish reversal 63% of the time. Slightly better than the hammer, and still a long way from a certainty.

Frequency rank: 12. It is one of the most common patterns in the catalogue. Overall performance rank: 84 out of 103. It therefore sits in the bottom quarter.

Those two ranks are read together and that is the main lesson here. A very frequent pattern is mechanically unselective: if it appears everywhere, it also appears in every case where nothing follows. Rarity is a form of selection, and the engulfing has none.

As with the other patterns in the catalogue, its best ten-day performance is measured to the downside, at -6.31% in a bear market with a downward breakout, and the associated rank is 14, far better than its general rank. Put simply: when this pattern fails, it fails fast and hard.

Three filters come out of the same work. Bullish engulfing candles located within the bottom third of the yearly low perform best. Tall candles are worth more than short ones. And it is better to avoid those appearing in a downward primary trend, which is the most counter-intuitive of the three, since that is precisely where you feel like taking them.

How to trade it

The classic entry is at the close of the second candle, or on a break of its high for a more cautious version. The second option costs entry price and removes part of the failures.

The stop goes below the low of the two candles, not below the body. And that is the practical problem with this pattern: an engulfing is worth more when it is tall, yet the taller it is, the further the stop. The quality filter and the cost of the trade pull in opposite directions, and you have to arbitrate every time.

The most useful filter remains position within the move. An engulfing at the bottom of an already long decline, in a zone the market has already defended, has nothing to do with an engulfing in the middle of a range. The pattern only timestamps the reversal, it does not cause it.

What it gives in your own journal

A performance rank of 84 out of 103 does not mean the pattern fails for you. It means it does not work on its own, across a sample of US stocks, with no filter. That is an important nuance and it is exactly what your journal can settle.

Tag your entries taken on an engulfing, then add a second label for those that met the position filter, meaning at the bottom of a move or in a defended zone. Compare the two groups. If the gap is clear, you have just turned a mediocre pattern into a useful sorting criterion, which is the best use anyone can make of it.

Also look at maximum favourable excursion on this pattern in particular. The measurements show that the moves that follow are often fast then run out of breath. If your journal says the same, a partial exit early is probably worth more than a distant target.

Tradoshi computes these measurements automatically on every imported trade, and labels combine in the journal filter.

Frequently asked questions

Do the shadows have to be engulfed too? No. The standard definition is about bodies and ignores shadows. If you require the extremes, you are counting a different pattern and your numbers compare to nothing.

Engulfing and harami, what is the difference? They are inverses of each other. In the engulfing, the second candle contains the first. In the harami, the first contains the second.

Why is its performance rank so low? Because it is very frequent. A pattern that appears everywhere also appears in every case where nothing follows. Frequency and selectivity work against each other.

Does the second candle need high volume? It is a widespread filter and consistent with the idea of a takeover, but it is not quantified in the study cited here. Verify it in your own journal before making it a rule.

Does it work on every timeframe? The figures cover daily data. Lower down, the pattern becomes very frequent and loses even more selectivity, which is already its weak point.
