Yesterday's rally above 1.5489 (now support) confirms the upmove from last week's low at 1.5285 to retrace recent decline has resumed and outlook is supportive for further gain towards 1.5590/00 before prospect of a pullback later this week.  
On the downside, below 1.5489 would signal a temporary top has been formed instead and risk correction to 1.5450/60 and possibly towards 1.5420.
