I am not sure if the pattern between the trendlines is a triangle but I treated it as a triangle. Trendlines drawn from highs and 3 lows. I remember reading somewhere that there should be at least 5 points touching the trendlines, not enough white space within the triangle and volume contraction as the pattern develops and surge in volume on break out, as the main criteria. Pattern on QLD seemed to meet all the criteria. Entered on the break of the triangle and exited on full extension.
