GBPUSD stays below the downward trend line on 4-hour chart, and remains in downtrend from 1.7190. As long as the trend line resistance holds, further decline could be expected after a minor consolidation, and next target would be at 1.6500 area. On the upside, a clear break above the trend line resistance will signal completion of the downtrend, then the following upward movement could bring price back to 1.7000 area.
