GBPUSD’s upside movement from 1.3039 extended to as high as 1.3448, breaking above the top trend line of the price channel on the 4-hour chart, facing a bearish trend line on the weekly chart. Breakthrough here could trigger further upside movement towards 1.3550, followed by 1.3657 (Sep 20 high) previous high. Near term support is at 1.3330, only a breakdown below this level could bring price back to the bottom of the channel.
