Just make a assumption that GBPUSD keep going down until it hit 1.2667-1.2712 this potential support zone . I personally will buy at this zone . For currently I don't make a 100% conclusion here . I think it will have a big green until price become stable at this zone with at least 3 days period . If we conclude 1.2666-1.2712 is a real support zone then the price will go up to first target 1.2965 and second target 1.3150 as well.
