GBPUSD is facing 1.6059 key support, a breakdown below this level will suggest that the uptrend from 1.5344 had completed at 1.6745 already, then the following downward move could bring price to 1.4500 area. However, as long as 1.6059 support holds, the price action from 1.6745 is treated as consolidation of uptrend, and one more rise towards 1.7000 is still possible.
For long term analysis, GBPUSD is in uptrend from 1.4230, further rise to 1.7000-1.7500 area to reach next cycle top on weekly chart is possible. Key support is at 1.5900, only break below this level could indicate that the rise from 1.4230 is complete.
