GBPUSD is in consolidation of the uptrend from 1.5854 (Nov 12, 2013 low). Another fall to the bottom of the price channel on 4-hour chart would likely be seen. As long as the channel support holds, the uptrend could be expected to resume, and one more rise towards 1.7000 could is possible. Only a clear break below the channel support could signal completion of the uptrend from 1.5854.
