A head and shoulders pattern can also occur at the market bottom. When it is at a bottom the formation is inverted, like someone upside down. Volume is usually highest during the left shoulder formation. As prices slip back, volume recedes, when a second rally forms, volume is again high, the head of the pattern is formed when surging prices and volumes begin to ease and fall back again. The trough between the head and the right shoulder must be below the peak of the left shoulder for the pattern to be considered a head and shoulder pattern.
