Dollar Yen had a deep move downside after the Fed Rate news.
No matter if it continues on downside or reverse to upside, there should be some kind of patterns at support levels to before next move.
The FIBO 61.8 was failed to hold the move down because of the very strong selling pressure, so that responsibility now is given to the FIBO 78.6. And look to the LEFT, there is support zone giving the FIBO 78.6 more power.
