The single currency maintained a firm undertone after yesterday's breach of 1.2354, suggesting erratic upmove from the 4-year low of 1.1876 has resumed and further gain to 1.2454 and then towards mesured target at 1.2570 is likely next week, however, daily chart res at 1.2673 should cap upside and yield retreat later.    On the downside, only a breach of 1.2242 would violate recent series of higher lows and higher highs from 1.1876 and signal a temporary top is made, bring pullback to 1.2168 support.
