GBPUSD is facing the resistance of the downtrend line on 4-hour chart, as long as the trend line resistance holds, the rise from 1.5707 is treated as minor consolidation of downtrend, and another fall to 1.5600 is still possible. However, a clear break above the trend line will indicate that a cycle bottom has been formed at 1.5707, then lengthier consolidation of downtrend could be seen.
