Most of the decline in the first two days.
The EURUSD is likely to close down for the fifth day in a row. Yesterday the pair close that 1.1125. The current price is trading at 1.1093 which is right on the 50% of the move up from the Jan 29 low (see chart below).
The lows today found support near the lows from Feb 4. That was the lowest low after breaking above the 200 day MA (currently at 1.10547). Was the low today a close enough test? Close support is the 5% retracement (basically on top of that). Look for support.
However, if the price moves below that level, in the new session the 1.1069 level and then the 200 day MA will a key area.
