An absence of any significant news in first half of the previous trading session expectedly led to a rebound from support zone located near the 112.10 mark. But then reports about agreement reached on tax reform by the House and Senate caused a spike up to the 112.70 mark.
As further path to the north is obstructed by the falling 100- and 200-hour SMAs together with the weekly PP, the Dollar is unlikely to gain much value against the Yen.
On the other hand, the 55-hour SMA in conjunction with the 50% Fibonacci retracement level should allow an active plunge as well. As a result, before the advent of some substantial news, the pair is expected to move horizontally between the above support and resistance barriers.
