What is Neckline?

Bo'yin chizig'i

In short

The line joining the lows between the peaks of a head and shoulders or double top (the highs, in the inverse patterns). The pattern is confirmed only when price CLOSES beyond it.

The neckline is the "trigger" of reversal patterns. In a head and shoulders or double top, it joins the lows between the peaks. In the inverse patterns (inverse head and shoulders, double bottom) it joins the highs between the troughs.

Why it matters

Until the neckline breaks, the pattern is not complete. Even with three peaks or two equal highs on the chart, price can bounce off the neckline and continue the trend. Hence the key rule: the pattern is confirmed only when price closes beyond the neckline — a brief intraday poke is not enough.

Slope

The neckline doesn't have to be horizontal; it can be slightly tilted. A downward-sloping neckline (in a head and shoulders) usually indicates weak buyers and therefore a stronger pattern.

After the break

  • Target: the measured move is calculated from the neckline — the pattern's height is projected in the breakout direction.
  • Retest: price often comes back to the neckline and tests it from the other side (retest). Old support becomes resistance — that is role reversal. Many traders enter on exactly this retest, because the stop can be closer.
Head and shoulders: neckline, target and volume
$90$100$110$120Neckline — $104Target: $104 − $16 = $88Left shoulder $110Head $120Right shoulder $111Break — exitRetestVolume

Head $120, neckline $104 — height $16, target $88. Volume shrank on each new peak and spiked on the break. Price came back to test $104 from below (retest) and failed — the last comfortable exit for anyone still holding.

Double top
$130$140$150Neckline — $140Target: $140 − $10 = $130Peak 1 $150Peak 2 $149.6ConfirmedRetestVolume

Two nearly equal peaks ($150 and $149.6), less volume on the second — buyers are tiring. The pattern was confirmed only by a close below $140. Height $10 → target $130. For a holder it is time to exit or tighten the stop.

Example

Illustrative (head and shoulders): left shoulder $112, head $120, right shoulder $113. The two lows between the shoulders sit at $104 — the neckline is $104.

  • Day 1: price drops intraday to $103.20 but closes at $104.60. No confirmation.
  • Day 2: price closes at $102.80 — below the neckline. The pattern is confirmed.

Measured target: pattern height $120 − $104 = $16 → $104 − $16 = $88. A week later price returns to $104 and fails to get above it — a retest. A trader entering there might put the stop not above the right shoulder but just above the neckline, say at $106: risk $2, distance to target $16 — R:R 1:8. The target is a guide, not a guarantee.

Mistakes and tips

  • Don't trade the pattern as "done" before the neckline breaks — bounces off the neckline are common.

  • The close decides, not an intraday poke. Some traders also require a 1–2% filter or two daily closes.

  • Waiting for a retest gives a better price, but in strong moves it may never come — accept that in advance.

Frequently asked questions

How do you draw a neckline?
In a head and shoulders, connect the two lows between the shoulders and the head (in a double top, the low between the peaks). The line can be horizontal or slightly sloped.
Why does price come back to the neckline after a break?
Traders who were trapped and new entrants become active at that level. Old support often turns into resistance, and price tests it once.
