AMZN has a great run over the past few months but the Bull side algos have seen a trend line break after 300 point series of trade. The most notable aspect to me is that the bull biased trading system has had very little profit over the last month. This tells me stealth selling is occurring. I have placed trend lines on the profit curves illustrate the reversal. Given the strength of AMZN traders who want to profit on a down move should wait for pops.
