AMZN didn't make a "top" signal over the last 8 months, instead it flagged while Amazon continued to have blow-out earnings. It has simply taken a break after a record breaking historical bull run. 4000 this year no problem.
Comment:
AMZN made its final dip just below the bottom trend line which I have found in recent years to be what I call a 'shake out before the breakout' signal. I believe MMs are making more and more attempts to fake out traders who pay attention to charts which is practically all of them as we traders have become very used to watching all the bull flags, pennants, wedges, etc. It is riding the bottom of the flag, this is going to really go soon!
