Rate drops to new lows in early New York today, aggressive liquidation by EURO-Sterling cross spreaders likely providing the main selling. Late longs are under pressure and can't ignore a break of the 50% fib defense numbers.
Bears took a stand at 1.4700 area last year and likely won't let go of shorts until technical levels are tested around 1.3660 area or lower which we have today. Technical traders will be looking for a test of the 100 day MA near-term to offer support this time after blowing through to the upside.
