The theme today has been the unwind of the US dollar strength from late last week.
It looks like a standard retracement to me and certainly nothing to undermine the USD bull market.
EUR/USD climbed today from support at the May low of 1.2797 and the high today is now flirting with the 38.2% retracement of the Thursday-Friday decline which comes in at 1.2884. Offers are lined in the 1.2880/90 zone with more at 1.2930/35.
