We said yesterday that the USDJPY could chop higher towards trendline resistance at 121.00 and the pair has skyrocketed the last two days and currently trades just above the figure (121.00).
Trendline resistance should be strong here but getting short is risky business until there is some sign that the pair has turned. Hourly RSI is at a momentum extreme (above 80), which makes it likely that any pullback will lead to a new high to create a divergence with the oscillator (rarely does a momentum extreme coincide with the actual high).
