GBPUSD is facing the support of the bullish trend line on the 4-hour chart. A clear break below the trend line support will indicate the upside movement from 1.2774 had completed at 1.3652 already, then the following bearish move could bring price back towards next support level at 1.3150. On the upside, as long as the trend line support holds, the fall from 1.3652 would possibly be consolidation of the uptrend and another rise towards 1.3950 is still possible after the consolidation.
