GBPUSD stays above a rising trend line on 4-hour chart and remains in uptrend from 1.5344 (Dec 28, 2010 low), the fall from 1.6277 treated as consolidation of uptrend. Sideways movement in a range between 1.6000 and 1.6277 would likely be seen in a couple of days, and uptrend could be expected to resume after touching the trend line. However, a clear break below the trend line support will indicate that the uptrend from 1.5344 had completed at 1.6277 already, then the following downward move could bring price to 1.5600 area.
