It is an assymetric head and shoulders. But the left shoulder is not prominent, and the right shoulder is very much lower than the top (head). I'll try to draw it, but don't know if this will work: HEAD + LS + + + +<waterfall decline
Wedges (ramps) are highly managed affairs, ALWAYS. Like a pampered and carefully pampered poodle. When the pool decides it has gone high enough, they will sell and then go short. The decline could be brutal.
I remember Gap and Limited back in 1987. They ramped those up in August. When the ramp ended, both fell off a cliff in early September, ONE MONTH before the market crashed. Gap, for example, went from $70 to $35 in days. After the crash, it was below $15.
