I had published an idea on GOOG in August suggesting one more decline to finish the correction. Here I am again suggesting the same. It looks like a double zigzag correction has unfolded... There should be a move to the lower channel line ahead...a pretty significant move.
Position a short on a retracement at a little higher price? You could use a price over the white trendline as a stop point.
