Head and shoulders
Head and shoulders is a candidate reversal structure with three peaks, the middle one higher than the shoulders, and a neckline through the intervening troughs. A specified break can activate a trading rule; a head-to-neckline distance projected from the break gives a theoretical measured move rather than a guaranteed target. The inverse structure uses three troughs with the middle one lowest. Breaks can reverse, and waiting for a retest changes timing and opportunity without guaranteeing a safer or better outcome. Define the structure and test the complete rule.
Example. An illustrative EUR/USD H4 pattern has a left-shoulder high at 1.1000, a head at 1.1080, a right shoulder at 1.1010 and a horizontal neckline through troughs at 1.0900. The head-to-neckline distance is 0.0180, or 180 pips. Projecting it below a 1.0900 break gives a reference target near 1.0720. Price breaks below the neckline but later returns above it: the initial break does not deliver the expected continuation. Waiting for a retest is a different rule, with potentially different entry prices and missed trades, rather than an inherently safer entry. The measured target is illustrative, not guaranteed. Define the structure and test any price or volume filter, noting that a retail FX feed does not show consolidated global volume.
Points and shoulders
Specify shoulder-height tolerance, bar separation and swing-confirmation rules. Visual symmetry is not a market obligation. Loose criteria can fit a known outcome; preserve the version recognised at decision time rather than replace it retrospectively.
Sloping neckline
Its value beneath the head can differ from its value at the break. Record where height is measured and from which break price it is projected. Without a convention, the same geometry can produce several apparently valid targets.
Trade risk
A break creates a signal candidate, not a complete plan. Measure the stop from the executed entry; commission and slippage alter payoffs. Retests can improve or worsen prices and miss some moves. Compare complete variants on a consistent sample.
FAQ
How is the head-and-shoulders target calculated?
Measure the head-to-neckline distance under a stated convention and project it down from the break. For a sloping neckline, specify the reference point. This is a theoretical measured move: some paths stop short and others go farther. It is not a guaranteed take-profit level.
What is the neckline?
For a conventional topping pattern, it joins the troughs between the shoulders and the head. It may be horizontal or sloping. Define what counts as a break and where the projected target is measured; the slope alone does not establish how reliable or bearish the pattern will be.
Is head and shoulders reliable every time?
No. A break can reverse and return above the neckline. A retest or another confirmation can change the rule but does not guarantee a better or safer outcome. Test the complete definition and costs rather than assume that recognising the shape is enough.
What is an inverse head-and-shoulders pattern?
It is the mirrored structure: three troughs with the middle one lowest, commonly interpreted as a candidate bottom after a decline. A defined upward neckline break and upward measured move follow the mirrored construction. Neither the break nor the target guarantees that price will rise.
