The USD/JPY bullish break could see price move towards the top of the bullish channel and the Fibonacci targets of wave 5 vs 1+3. This breakout could be part of an impulsive third wave (purple) whereas a bearish breakout could indicate a pauze or end of the uptrend.
The USD/JPY seems to have completed a bearish ABC (orange) pattern within wave 4 (green). A break above the local resistance level (orange) could start the USD/JPY upside for a wave 5 (green) of wave 3 (blue) and see price move higher towards the Fibonacci targets of wave 3 vs 1.
