EURUSD is slicing lower on the new bout of risk aversion to open the week and ahead of a possibly dovish Trichet on Thursday. Online forex sees a key level comes in just above 1.3100, the 100-day moving average (not an important MA recently, but was very influential in recent years), and also the 50% retracement level for the recent rally to north of 1.3700. Below that, the psychologically important 1.3000 level looms.
