dis-correlation term interval.
I think both currency pairs are still in a correlation term. Therefore if EUR/USD will crash down,
USD/JPY will also crash down.
In addition to that, USD/JPY is having its own chart pattern between:
A--daily wave pattern since 105.44
B--4 hours candle wave pattern since 102.79 (Jun. 04)
