Bullish Harami: the pattern engulfing gets compared against

A bullish harami is the opposite shape from an engulfing pattern — a small body inside a large one — and reads as contraction, not reversal on its own.

What it measures

A bullish harami is a large down bar followed by a small up bar whose entire body sits inside the prior bar’s body — the reverse containment of an engulfing pattern.

It measures a sudden drop in participation after a strong move: the second bar could not extend the first bar’s range in either direction.

How it is calculated

These are the steps Basis performs, verified against the published definition.

  1. 1

    Bar one is a large down bar.

  2. 2

    Bar two opens above bar one’s close and closes below bar one’s open — its body sits fully inside bar one’s body.

  3. 3

    The smaller bar two is relative to bar one, the more pronounced the contraction.

How to read it

  • The pattern says selling pressure stalled, not that buying pressure has taken over — it is a pause signature, weaker by construction than an engulfing pattern.
  • It is more useful as an early warning to tighten risk on an existing short than as a standalone long entry.
  • A harami cross — where the second bar is also a doji — is a more extreme version of the same stall and is read the same way, more strongly.

Where it misleads

Because the second bar is small by definition, a bullish harami produces many false positives in choppy conditions where small bars are common regardless of any real change in control.
