GBPUSD is technically in an uptrend under the overall downtrend in the big pictures., we've price trading above this ascending wedge while forming up another ascending wedge at the resistance zone of the long holding overall downtrend, a break below or above this ascending wedge will tell us the next direction.
If price break below then 1.2600 zone will be expose as next level of support, if otherwise we have a break above as i'm anticipating then 1.3500 will expose as next zone of resistance.
