The single currency maintained a firm undertone and a breach of overhead resistance at 1.3736 would signal another leg of corrective upmove from this month's low of 1.3433 has taken place and bring further gain to 1.3780/90, however, key daily resistance at 1.3840 should remain intact and yield retreat later.  
Onthe downside, only a breach of 1.3621/26 would signal a top is made and bring pullback to 1.3596 and then towards strong support area at 1.3530/37.
