GBPUSD broke above the upper line of the price channel on 4-hour chart, indicating that lengthier consolidation for the downtrend from 1.5785 is needed. Range trading between 1.5034 and 1.5300 would likely be seen in a couple of days. However, as long as 1.5300 resistance holds, the downtrend could be expected to resume, and one more fall towards 1.4500 is is still possible after consolidation.
