GBPUSD stays below the downward trend line on 4-hour chart, and remains in downtrend from 1.6524, as long as the trend line resistance holds, the rise from 1.5951 could be treated as consolidation of the downtrend. Another fall could be expected after consolidation, and next target would be at 1.5600 area. On the upside, a clear break above the trend line resistance will indicate that the downtrend had completed at 1.5951 already, then further rise to 1.6400 area could be seen.
