I’m not sure how to post a picture up, but if you look at the USD/JPY currency in 60 min, it seems like a triangle is an ascending triangle. The bottom line starting on 6/5/09 and come up to todays point and the top can’t break free.
I could wrong, but maybe more knowledgeable people can tag in on this
It also seems like on previous times where something similar has started to form it seems to drop short.
