The 1.5705/1.6693 bounce is being corrected in fast and furious fashion today. Prices have slipped through the 38.2% retracement of that rally the same day as making the top of the rally, never a good sign.
The 10-day moving average at 1.6260 and the 1.6240 support level lie within reach if thin Friday markets decide not to put up a fight. Cable trades now at 1.6305.
