GBPUSD is facing the downward trend line on 4-hour chart. A clear break above the trend line resistance will indicate that the downward movement from 1.6593 had completed at 1.6309 already, then the following upward movement could bring price to 1.7000 area. On the downside, as long as the trend line resistance holds, the rise from 1.6309 could be treated as consolidation of the downtrend from 1.6593, one more fall to 1.6270 area to complete the downward movement is possible.
