The Euro has rallied vs the USD every day this week but is expected to come under pressure amid a wave of upcoming Euro CPI data. The Euro is having trouble making a lot of headway past long term trend line resistance set back from 2008. Until a reversal candle is produced it is best to stick to the sidelines on this pair or place smaller than normal trades.
The fact that the ECB has made it clear that QE is not a major consideration at this point is the main reason for Euro strength. It is best to wait for a better setup to place a trade on this pair.
