Looks like there are accounts happy to book profits on the approach of 1.3894, the 61.8% retracement of the drop from 1.5145 late last year through the lows in June.
Equity markets have shed early gains and commodities are seeing a bit of profit-taking so perhaps we have beaten the quantitative ease horse to death. Bears watching whether today is a day to book profits after a long USD slide.
EUR USD dips are shallow so far, only to the 1.3850s.
