Euro fell in European trade for another session against dollar off six-month highs on profit-taking.
Dollar was boosted after strong US services data for November, which boosted bets for a 0.75% rate hike next week.
EUR/USD fell 0.15% to 1.0475, with a session-high at 1.0518, after closing down 0.5% yesterday, the first loss in four days on profit-taking off six-month highs at 1.0595.
Euro rose 1.4% last week, the second weekly profit in a row against dollar as concerns about a widening policy gap between the US and Europe fade.
The dollar index rose 0.3% on Tuesday for the second session off six-month lows at 104.11 against a basket of major rivals.
Recent US data showed US services PMI rose unexpectedly last month, showing the services sector remains vibrant.
Such data raised chances of a 0.75% rate hike by the Federal Reserve from 18% to 22% next week.
