This pattern tells you about bullish/bearish trend reversal. A head and shoulders pattern is comprised of three component parts: After long bullish trends, the price rises to a peak and subsequently declines to form a trough. The price rises again to form a second high substantially above the initial peak and declines again. The price rises a third time, but only to the level of the first peak, before declining once more. The first and third peaks are shoulders, and the second peak forms the head. The line connecting the first and second troughs is called the neckline.

A pattern in head and shoulder trading that provides sell/buy signals. And its confirmation is about 90%.
I think that that is one of the most recognizable patterns which is applied in trading. You'd better watch the videos about that, you can google or find videos on youtube. Basically, the patter is pretty easy to understand and it is pretty reliable, however, it is quite a rare occasion when you can see it in real time trading.
