GBPJPY: Weekly Chart

Here in the weekly chart, you can see the uptrend was clearly broken and the retracement corrective wave (B) has begun.

WAVE COUNT
The wave (A) was a 5-wave move up. Since I am seeing the larger corrective phase as being possibly a 5-3-5 ABC zigzag, then it follows that wave (B) must be 3-waves. If so, then the wave A, when completed, wave B will commence back up. More than likely to retest that broken trend channel and also retest the highs.

PATTERNS
There is a POTENTIAL Crab that formed as the trend channel was broken. As wave A of (B) dropped, it almost but not quite filled that crab. So it is still a POTENTIAL Crab.
