We're seeing more US Dollar buying as European trading gets fully underway 5 May 2016

EURUSD has punched its way through 1.1470-75 support and triggered stops to post 1.1451.

More bids/demand at 1.1450 but stops now reported below 1.1440 and that could bring the next wave of support at 1.1420 into play.

We have two large-ish option expiries at 1.1475 and 1.1500 and the price action so far, as well as the general USD demand, would suggest that the writers have an interest to keep it below those levels at the 14.00 GMT expiry.
