# Pattern – Part1: Head and Shoulders

Analyzing candlestick charts, it is possible to identify patterns, or figures, that allow us to hypothesize, with a certain probability, the price trend.

The patterns are divided into two large families : trend inversion patterns and continuation patterns.

The main inversion patterns are:

• double minimum / maximum
• triple minimum / maximum
• maximum / minimum rounded off
• Formation of a V

The main continuation patterns are:

• Triangles
• Rectangles
• wedges
• Flags and Guidons

We will divide the treatment of the various patterns into more articles.

The head and shoulders is one of the main inversion patterns , and it is also the one that, if completed, is most likely to predict an inversion.

In the event of an uptrend , the basis points are as follows:

• existence of an up-trend;
• subsequent occurrence of exaggerated increases;
• three consecutive rises (the two shoulders and the head).

More in detail, the figure is formed as follows:

• Left shoulder:
• shape: the wave follows the previous uptrend;
• volume: they are high at the beginning, until there is a downsizing given by the meeting between supply and demand;
• shape: has a wider movement than the shoulder;
• volume: volume are on average lower than the left shoulder. In fact, a divergence between rising prices and falling volumes is created, leading to the downsizing of prices which creates a relative minimum;
• Right shoulder :
• shape: formed for the most part due to sales made in the previous downhill phase;
• volume: growing.

It is important to know that starting from the minimum of the left shoulder and arriving at the minimum of the head you can trace the neckline .
The neckline is important for the following reasons:

• the figure is completed when the neckline is clearly exceeded;
• the probability of this figure is also due to the divergence of the inclination of the neckline with respect to the trend of origin;

The head and shoulders can also be in horizontal phases but with less clear consequences.

The occurrence in the case of is also interesting   bearish trend , in which one has abottom head and shoulders.

The graphic formation is similar but overturned, in detail:

• The left shoulder is formed as a result of a decrease in prices that occurs with volumes sustained and subsequently with a recovery in prices with low volumes.
• The head has a further decrease in prices, accompanied by very low volumes.
• Finally, the right shoulder is formed with sustained volumes, which increase even more once the neckline has been overcome.

The bottom head and shoulders usually occurs at the end of a primary descending trend.
