Although euro has retreated after last week's rise to 1.4051 and minor consolidation is envisaged, as price action from there looks corrective, reckon 1.3920/30 would limit downside and bring resumption of recent upmove for re-test of said resistance and later towards 1.4120/30.  
  
Below support at 1.3898 would indicate temporary top has been formed instead and risk stronger correction to 1.3840/50 before prospect of a rebound.
