Euro's selloff from 1.4328 (last Thursday's high) in line with dollar's rise versus most other majors signals the early rise from 1.4086 has ended there and a re-test of said support is envisaged, below would confirm the recent decline from this month's top at 1.4448 has resumed and further weakness towards 1.4000 would follow.  
On the upside, a firm breach of 1.4200/10 would indicate further choppy trading is in store and risk a rebound towards 1.4252 (previous support now resistance).
