GBPUSD remains in uptrend from 1.6692, the fall from 1.7176 is likely consolidation of the uptrend. Key support is now located at the lower line of the price channel on 4-hour chart. As long as the channel support holds, the uptrend could be expected to resume, and another rise towards 1.7300 is still possible. On the downside, a clear break below the channel support will indicate that the uptrend had completed at 1.7176 already, then the following downward movement could bring price back to 1.6850 area.
