Engulfing: compare bodies, then test the idea
The new body covers the old one, yet its high is lower. Can it still be engulfing?
Apply a precise body-containment rule and keep failure in the record.
An engulfing pattern compares two real bodies. Covering the first body does not mean the next move is guaranteed or that both wicks must be covered.
For our bullish engulfing rule, a bearish candle is followed by a bullish candle whose open is below the first close and whose close is above the first open. This fully covers the first real body. We use strict boundaries; another definition may allow equality.
The wicks do not need to be engulfed under this body rule. The bearish counterpart reverses the colours and inequalities. Body containment and an outside bar, where the whole high–low range expands beyond the previous range, are different tests.
Record the prior trend and any zone before seeing the second close. A candidate after a decline is a different hypothesis from the same shape in the middle of a range. The second candle must finish before its final body is known.
Specify confirmation, invalidation, paper quantity and costs separately. If a later price breaks the idea, keep both the recognised pattern and the failed outcome. A chart shape does not prove institutional intent, guarantee a fill or remove slippage risk.
Let’s work through it
- Compare the two completed open–close intervals.
- Check direction, prior context and the exact boundary convention.
- Record the subsequent test, including failures and no-trades.
Let’s use numbers · hypothetical example
In fictional units, candle A is O=105, H=106, L=100.5, C=101. Candle B is O=100.8, H=105.8, L=100.6, C=105.2. B's body 100.8–105.2 covers A's 101–105, although B does not cover A's wicks. If the written idea is invalid below a later close of 100.5, a close at 100.4 invalidates it. The original pattern does not disappear.
Easy mistakes to watch for
- Requiring wick coverage while claiming to test a body rule.
- Counting a recognised pattern as a completed profitable trade.
- Removing failed examples after the future becomes visible.
Keep in mind
A body pattern is not a measured probability of reversal. Different feeds or candle boundaries can change whether a rule qualifies.
Your turn
Change only candle B's open to 102. Does its body still cover 101–105? Then explain why the later 100.4 close must remain in the review.
A quick check before we move on
Does B fail the body rule merely because its high 105.8 is below A's 106?
- No; B's real body still fully covers A's body
- Yes; all engulfing rules require both wicks covered
- No; therefore a profit is guaranteed
Check answer
No; B's real body still fully covers A's body Our stated rule compares 100.8–105.2 with 101–105. The wick extremes are not its containment test, and qualification does not guarantee profit.
