The Head & Shoulders pattern is an accurate reversal pattern that can be used to enter a bearish position after a bullish trend. It consists of 3 tops with a higher high in the middle, called the head. The line connecting the 2 valleys is the neckline. The height of the last top can be higher than the first, but not higher than the head. In other words, the price tried to make a higher high, but failed. The closer the 2 outer tops are to the same price, the more accurate the pattern.
If the price breaks the neckline and closes below it, the pattern is complete. Conservative traders may look for additional confirmation. The target can be estimated by measuring the height of the pattern (from the neckline to the head) and projecting this downwards. Common stop levels are above the neckline or above the right shoulder. The Inverse Head & Shoulders is the bullish version of this pattern that can form after a downtrend.
