GBP/USD recently rallied up to test 1.51642, a price point previously tested @ 10am GMT, thus far it has failed to break through. With today's daily high @ 1.5190, lower than yesterdays, this may suggest a swing high occured yesterday making conditions optimal for short entry.. Pattern will be confirmed if price doesn't breach 1.51642 during Asian session and continues down to break through the ascending neckline.
