I would say that USD/JPY has already formed its Big H&S formation. Condition: present rebound wave should be below LS 1--RS trend line.
If we assume H&S with (LS 1--Alt.RS ), it has already broken its neckline at 117.87. If we assume H&S with (LS 1--RS ), it needs a breakdown about 117.70 area again.
In these case, minimum target of H&S breakdown will be at 113.66. And target of H&S with (LS 1--RS ) will be at 113.33.
