After a prolong uptrend, when Head & Shoulder appears it is normally deem as a form of topping pattern by the bulls However, at times when the right shoulder neckline breakout downwards, drop less than 10%, reverse and continue upwards and finally has a close above the head.
Statistically, price can gain as much as 31%. If that is the case, we might see another ultimate higher high before the real collapse!
