GBPUSD is facing the resistance of the downward trend line on 4-hour chart. As long as the trend line resistance holds, the downtrend from 1.3445 could be expected to resume, and further decline to test 1.2865 support is possible. On the upside, a clear break above the trend line resistance will indicate that the downtrend had completed at 1.2946 already, then the following upward movement could bring price to 1.3400 zone.
