I Should Have Noticed This Pattern (Episode 1)

Just today I zoomed out on my GS chart and noticed for the first time this almost perfect triangle pattern. How did I completely miss this?
-There are many times in my short trading career that I have come across things I should have noticed. Whether it's chart patterns, correlation, volume spikes, or indicators indicating; I kick myself for my neglect!

-Now the least I can do is point out those mistakes and share them with you as I see them, in the hopes that more get noticed in the future.

-This is an example of a symmetrical triangle which is considered the most common type of triangle pattern. Despite the name, the triangle does not have to be symmetrical and like all patterns is evaluated in the approximate. Some imagination is required. Most triangles are a representation of consolidation before continuation, but can sometimes represent a top or bottom before reversal. When price does break out of a triangle, volume should spike and this example clearly shows that. This example also shows a false breakout which would have been discovered when closing for the day back "inside" the pattern. Also like all patterns, the larger the time interval, the more important the pattern. Daily and longer are preferred.

-Again this is what I see after the fact and far too late. I would not enter this trade now. Please let me know if I missed something or if you were able to trade this in real time and there was details that I left out. Also, did anyone make money on noticing this pattern? Am I mistaken in any way?
