Despite euro's rebound from yesterday's low at 1.3748, price action from there is viewed as a retracement of recent decline and reckon 1.3940/50 would limit upside, bring another fall but breach of intra-day support at 1.3806 is needed to signal correction has ended and yield re-test of aforesaid low later.  
Above 1.3965/70 would abort this bearish scenario and risk further gain to 1.4000 but resistance at 1.4041 should cap upside.
