A head and shoulders pattern is also a trend reversal formation. It is formed by a peak (shoulder), followed by a higher peak (head), and then another lower peak (shoulder). A “neckline” is drawn by connecting the lowest points of the two troughs. The slope of this line can either be up or down. In my experience, when the slope is down, it produces a more reliable signal.
In this example, we can visibly see the head and shoulders pattern. The head is the 2nd peak and is the highest point in the pattern. The two shoulders also form peaks but do not exceed the height of the head.
With this formation, we look to make an entry order below the neckline. We can also calculate a target by measuring the high point of the head to the neckline. This distance is approximately how far the price will move after it breaks the neckline.
You can see that once the price goes below the neckline it makes a move that is about the size of the distance between the head and the neckline.
