The danger of tunnel vision

I was soooo disappointed that the top of the range came up short
I missed one of the best trades that can be found ---
A second wave Gartley ! And this one hit almost to the pip. This is what can happen when you let yourself become
married to an idea/trade and stop letting the "market" tell you what is going on.
Where's the next trade ? (after a few seconds of muttering under my breath: How could i have missed that trade ???)
