The EUR selling comes with the background of the ECB looking to ease further in December, while market consensus is well advanced in the direction of looking for a Fed 'lift off' rate hike, also in December.
Rallies in EUR/USD are thus presenting as sell opportunities.
From here for EUR/USD, we will be running into technical support soon enough, 1.0675 or thereabouts shaping up as a level (technical analysts, comments welcome) ... it does look heavy though.
