USD/JPY flirts again with the downtrend line signaling that the buyers are very strong and that an upside breakout is imminent. You can see that the pair has registered false breakouts in the past, that's why we should wait for a valid one confirmed by a new higher high, jump above the former high.
So, I believe that we'll have a great buying opportunity if USD/JPY jumps and stabilizes above 104.40. Technically, the price's failure to come back down towards the downside line indicates that the downtrend is over.
Trading Conclusion!
A buying opportunity could appear if USD/JPY passes above the 104.40 level. Such a breakout signals further growth towards 106 and 107 levels.
