## Samenvatting
Trade het meest betrouwbare reversal patroon. Head & Shoulders signaleert trenduitputting en omkering.

Het Head and Shoulders patroon is één van de meest betrouwbare reversal signalen in technische analyse. Het vormt aan het einde van stijgende trends: linker schouder (piek), hogere piek (hoofd), lagere piek (rechter schouder), verbonden door neckline support. Wanneer prijs de neckline breekt, signaleert het trendomkering met prijsdoel = neckline - (hoofd - neckline).

## Kernprincipes
- Pattern must form after extended uptrend (or downtrend for inverse)
- Right shoulder should not exceed head height
- Volume decreases through pattern, spikes on break
- Neckline break confirms the reversal

## Instap-regels
- Identify complete H&S pattern (left shoulder, head, right shoulder)
- Enter on neckline break with volume confirmation
- Or enter on retest of broken neckline
- Uptrend must precede pattern

## Uitstap-regels
- Target = Neckline - (Head height - Neckline)
- Stop loss above right shoulder
- Partial profit at 50% of measured move
- Exit if price reclaims neckline

## Risico's
- Stop loss 2-3% above right shoulder
- Position size based on stop distance
- Wait for volume confirmation on break
- Don't trade incomplete patterns

## Anatomy of the Head and Shoulders Pattern
The Head and Shoulders pattern is technical analysis's most recognizable reversal signal, appearing at the end of uptrends when buying exhaustion sets in. Understanding its anatomy is crucial for accurate identification and trading.

The pattern consists of four key components. The Left Shoulder forms when price makes a new high, then pulls back to a support level. This pullback establishes the beginning of what will become the neckline. The Head forms when price rallies again, exceeding the left shoulder's high, then retreats back toward the same support level. This creates the highest point in the pattern. The Right Shoulder forms when price attempts another rally but fails to reach the head's height, showing weakening momentum. Finally, the Neckline connects the lows between the left shoulder-head and head-right shoulder, serving as the critical support level.

Thomas Bulkowski's research on over 10,000 patterns found that the most reliable Head and Shoulders patterns have symmetry—right shoulders that mirror left shoulders in height and width. Patterns where the right shoulder is significantly smaller than the left have higher failure rates.

## Inverse Head and Shoulders: The Bullish Mirror Image
While the classic Head and Shoulders signals bearish reversals at market tops, the Inverse Head and Shoulders (or Head and Shoulders Bottom) signals bullish reversals at market bottoms. Everything is flipped upside down.

In an Inverse H&S, the Left Shoulder forms as price makes a new low, then bounces to resistance. The Head forms when price drops even lower than the left shoulder, then recovers to the same resistance zone. The Right Shoulder forms when price drops again but fails to reach the head's depth, showing that selling pressure is exhausting. The Neckline connects the highs between each component, now acting as resistance.

Bulkowski's data shows Inverse Head and Shoulders patterns actually have a slightly higher success rate (89%) than bearish H&S patterns (83%). This may be because bottoming patterns benefit from capitulation selling—when the last weak holders panic out, there's literally no one left to sell. The neckline breakout confirms the reversal, with the same measured move calculation: distance from head to neckline, projected upward from the breakout point.

## Measuring Price Targets with Precision
One of the Head and Shoulders pattern's greatest advantages is its built-in price target. This isn't arbitrary—it's based on the concept that price 'remembers' the distance it traveled and tends to move similar distances after breakouts.

The measured move calculation is straightforward: measure the vertical distance from the head's peak to the neckline, then project that same distance below the neckline breakout point. For example, if the head peaks at $100, the neckline is at $90, and price breaks the neckline, your target is $80 ($90 - $10 = $80).

Bulkowski's research shows that price reaches the full measured move target approximately 55% of the time. However, price reaches at least half the measured move target 75% of the time. This suggests a conservative strategy: take partial profits at 50% of the measured move, then trail stops for the remainder. For inverse H&S patterns, the calculation works identically but projects upward from the neckline breakout.

## Volume Confirmation and Common Pitfalls
Volume behavior throughout the Head and Shoulders formation provides critical confirmation signals—and ignoring volume is the most common mistake traders make.

Ideal volume progression: highest volume on the left shoulder (strong buying interest), lower volume on the head (buying exhaustion despite higher prices), even lower volume on the right shoulder (momentum clearly fading). Then—crucially—volume should spike dramatically on the neckline break. This volume expansion confirms institutional selling and validates the pattern.

Common pitfalls to avoid: Trading before the neckline breaks (the pattern isn't confirmed until the break—many patterns fail when price bounces off the neckline). Ignoring volume (a neckline break on low volume often produces false breakdowns and quick reversals). Forcing patterns (not every three-peak formation is a valid H&S—the neckline should be relatively horizontal and form after an extended uptrend). Setting stops too tight (place stops above the right shoulder, not just above the neckline, to avoid being stopped out by normal volatility).
