The head and shoulders is a reversal pattern. It appears at the top of an uptrend and warns that buyers are running out of room. Price makes a high, a higher high, then a lower high — three peaks, with the middle one tallest — and once it breaks the level underneath, traders read the trend as turning down. Flip the whole shape upside down at the bottom of a downtrend and you have the inverse version, which signals a turn up.
What it is
The pattern has four parts:
- Left shoulder — a peak inside an existing uptrend, followed by a pullback.
- Head — a higher peak, then another pullback to roughly the same level as the first.
- Right shoulder — a lower peak that fails to reach the head, showing buyers are weakening.
- Neckline — the line joining the two pullback lows beneath the shoulders.
The neckline is the level that matters. Until price closes below it, you have three bumps on a chart and nothing more.
How it's traded
Most traders wait for a close below the neckline rather than acting on the right shoulder, which can only be named a shoulder in hindsight. Two common entries:
- On the break — enter as price closes below the neckline.
- On the retest — wait for price to break, come back to touch the neckline from below, then turn away. Fewer of these fill, but the failed ones are cheaper.
The stop usually sits above the right shoulder. If price climbs back over it, the reversal has not happened.
Setting a target
Measure the height from the head down to the neckline, then project that same distance below the break.
Say GBP/USD makes a head at 1.2900 with the neckline at 1.2700 — that's 200 pips. Subtract it from the neckline and the target is 1.2500. At £10 a pip, that move is worth £2,000 if it reaches. A stop above the right shoulder, 100 pips away, risks £1,000 — so you're paying £1,000 for a £2,000 target, a 2:1 shape before you allow for the trades that fail.
The measured move is a target, not a promise. Plenty of breaks travel half the distance and stall. Treat it as where you'd take profit if the market gets there, not as a figure you can bank.
False breaks
The pattern's main failure is the false break: price closes below the neckline, triggers entries, then reverses straight back through it. Forex has no central volume figure to lean on, so confirmation comes from the close — a candle that finishes clearly below the neckline on your timeframe, not a wick that pokes through and recovers. A neckline retest that holds gives you a second, cleaner read. Patterns on a 4-hour or daily chart hold up better than the same shape on a 5-minute chart, where noise manufactures shoulders that mean nothing.
The Karnek note
Karnek doesn't spot patterns or place orders — it's read-only and can never trade your account. What it does is record every trade your strategy takes off a head and shoulders so you can check, over a real sample, whether those setups pay. A pattern that looks clean on one chart is only worth trading if the numbers hold across dozens.
