As called, the gap filled. But now just a narrow band of support around $600 level till rising MA(200)d at about $589.93. With this warning, there will be much sell pressure overhead, so longs will be cautious on this bounce.
If one looks at a broader daily chart w/ today including afterhours, we see a snap back bear rally to the MA(50)d, that was then crushed back to a new period low with volume. Looking like a sure inverted hammer.
Things get very mushy until a $600 level gap fill.
