A pattern in price trends which chartist consider indicates a price trend reversal. The price has risen for some time, at the peak of the left shoulder; profit taking has caused the price to drop or level. The price then rises steeply again to the head before more profit taking causes the price to drop to around the same level as the shoulder. A further modest rise or level will indicate that a further major fall is imminent. The breach of the neckline is the indication to sell.
