I have a way with remembering chart patterns, and I especially remember this one.
I think the patterns are extremely similar and I'm showing my raw research. Sometimes people post comparisons of markets to other bubble markets and try to make a pattern fit. I remember chart patterns and thought this was useful, if not purely entertaining. The way to trade this pattern would be based on solid trading principles. And since I like to sell on new lows, my way of trading it would be to sell on weakness under the most recent daily lows.
