The USD is in a mark-up phase (green shaded area). This phase is characterised by a bullish EMA formation. I.e. the green 5-day EMA is above the orange 13-day EMA, and the orange 13-day EMA is above the black 34-day EMA. The RSI(9) is above 80, so a pause or pullback at this level is possible as the oscillator normalises.
Consulting the weekly chart below confirms the mark-up phase:
The weekly chart shows a mark-down phase for the most part (red shaded area). However, the USD is now above its 30-week EMA and the 30-week EMA has turned up. Thus, the longer-term time frame confirms the mark-up phase.
It is interesting to note that Fed Chair Powell did say when he spoke this morning that some investors are not well positioned for anticipated rate hikes. This pushed the USD higher and market sentiment tends to be thinking another 3 rate hikes for 2018, making it a possible 4 rate hike year.
