I've heard that's the harmonic pattern with the highest success rate, but I'm not sure it is. The problem is that the Shark pattern is very similar, but D is at 88.6% or 113% of XC. To decide between both, we can analyse the CD leg. We look at the first retracement and when it is over, we use the 100%, 127% or 161% extension. Here the 161% extension is at 102.03, so it is more likely a Cypher.
Thanks, I'm going to give this some further study also. Do you also know of any rules for time retracements? And maybe we could pitch this pattern to AMP monitor, it's a quite useful service for harmonic pattern screening http://en.ampmonitor.com/amp
