Being contained by 1.6059 support, GBPUSD rebounded from 1.6078, and formed a cycle bottom on 4-hour chart. Range trading between 1.6078 and 1.6250 is expected in a couple of days. Key resistance is at downtrend line from 1.6546 to 1.6441, as long as the trend line resistance holds, one more fall to re-test 1.6059 support is still possible. However, a clear break above the trend line will indicate that the fall from 1.6546 had completed at 1.6078 already, then another rise towards 1.6745 previous high could be seen.
