GBPUSD remains in uptrend from 1.5344 (Dec 28, 2010 low). As long as the trend line support holds, the fall from 1.6277 is treated as consolidation of uptrend, and one more rise to re-test 1.6298 (Nov 4, 2010 high) is still possible after consolidation. On the downside, a clear break below the trend line support will indicate that the rise from 1.5344 had completed at 1.6277 already, then the following downward move could bring price back to 1.5600 area.
