Engulfing candle: does it work after costs?

One candle completely covers the body of the previous one. Courses say it marks a turn.

No detectable edge after costs

Verdict

No detectable edge after costs

Applied mechanically to 29 coins, this rule showed no detectable edge after costs: the average is within the range of luck, and it does not beat entering at random in a way that holds up.

What courses teach

The idea

The best-known two-candle reversal. After a decline, a large up candle whose body covers the previous down candle is called a bullish engulfing, and is taught as a sign that buyers took over. The reverse is bearish engulfing.

The rules we froze

These numbers are the usual textbook values. They were written before we saw a single result and were not changed afterwards.

PartRule, fixed before the test

Signal

The body of the signal candle covers the body of the previous candle in the opposite colour, is at least 0.5 ATR, and follows a move of at least 2 ATR against it in the previous 6 candles.

Entry

Market order at the close of the signal candle.

Stop

Beyond the low (or high) of the two candles. At least 1 ATR from entry.

Target

Twice the distance to the stop (2R).

Time limit

Closed after 60 candles (10 days) if neither stop nor target was hit.

Costs

0.14% round trip plus real funding, charged on every trade.

What it looks like

Examples, good and bad

Two real trades picked by a fixed rule, not for being pretty, and six drawn at random from the held-back period (the most recent two years). 0 of the 6 won. Examples show the rule, they are not results: the results are the numbers further down.

All 2,720 trades added up, with the three periods shaded. The right axis shows euros if you risked €100 on each trade. The dashed line is what random entries would have done.

By period

The same average, split by period. The black bars are the 95% range: if they cross zero, we cannot tell the result from luck.

How the trades ended

The honest yardstick

Compared with entering at random

A pattern should beat luck, not zero. We ran 1,000 simulations that enter at random times on the same coins and periods, in the same direction, with the same stop distance, target and time limit.

Engulfing candle compared with random entries

In plain words

Why the numbers look like this

Random entries lose too. Entering at random times with the same stops and targets averaged -4.5% per trade (-0.045R) because of fees, funding and spread. The pattern averaged +0.0% and did better than 96% of 1,000 random runs. That is the honest comparison: not zero, but what luck plus costs produce.

Before costs: +3.8%. After costs: +0.0%. Fees, funding and slippage took 3.7% of the amount risked from every trade, on average. The signal has a small raw tilt, and costs eat it.

Win rate versus break-even. It won 35.8% of trades. With average wins of +1.830R and losses of -1.022R, it needed 35.8% to break even. The win rate is about what it needs, so the average is about zero.

Opposite side, same stops. Taking the opposite direction on every signal, with the same stop distance, averaged -2.0%. If the pattern carried real information, the pattern direction should beat its mirror by a clear margin. Here the gap is 2.1 percentage points.

Consistency across time. The average was positive in 1 of 3 periods. A real edge should not depend on which period you look at.

Sensitivity. Across 32 variations of the rule, 13 were positive and 19 negative. The best variation (+6.1%, 1,256 trades) is not a result: with 32 variations, a few green cells appear by chance. We look for a broad green region.

Stress tests

Does it survive changes?

Changing the pattern shape

Each cell is the same test with a different setting. The outlined cell is the rule we froze. Green is positive, red negative. We do not pick the best cell: we look for a broad region.

Changing the exits

Same idea for the target and the stop.

Coin by coin

15 of 29 coins had a positive average. With a few dozen trades per coin, some are always positive by chance.

Limits

What this does not say

It does not say engulfing candle never works. It says this version of the rule, applied to every case, shows no detectable edge after costs in this data.
It is a simulation. Real fills, delays and emotions make results worse.
The market may change. Results from the past are not a forecast.

Questions

Questions about engulfing candle

Does engulfing candle work in crypto?

In our test of 2,720 trades on 29 crypto perpetuals, with real costs and funding, the average result was +0.000R per trade (+0.0% of the amount risked). Verdict: no detectable edge after costs. This applies to the textbook rule defined on this page, not to every way of using it.

Why do I see charts where engulfing candle worked?

Because any rule produces winning examples. A chart that shows a winner says nothing about how often the same rule fails. The test above applies the rule to every case, with costs, without picking.

What would make this result change?

A different timeframe or market, different exits, or filters that add information the pattern does not contain. We tested a second timeframe and 32 variations of the rule; the numbers are on this page.

How should I read the percentages?

They are percentages of the amount you risk per trade, not of your account or of the coin price. +0.0% means +0.0% of the amount risked, on average. See what is R.
