Amazon changing sentiment in front of earnings

Amazon was in down trend most part of the time this year but caught some buying after it broke up from $320-$340 consolidation with strong two days continuation to $359.32. Now, it holds nicely near highs. Buyers probably should not gave back more than 1/4-1/3 of this recent move if they want to see quick continuation. I expect to see bull flag and continuation through recent highs some time soon. maybe earnings release on Thursday 24 after market close could be such type of catalyst.
