I believe greater confidence is with the pattern that jives with Elliott Waves. This is why I've been combining both methods for over 15 years. It's far from perfect but I failed in trying to use just patterns starting in 1997 and failed in trying to just use EW. Then in 2003, combined the two.
The 15 min chart to me shows more a completed and confirmed wedge. A breakout jives well with the next impulse count on EW.
