GBPUSD's rise from 1.5602 extends to as high as 1.5913. Further rise to test 1.5991 previous high resistance would likely be seen later today, a break above this level will signal resumption of the uptrend from 1.5236 (Jan 13 low), then next target would be at 1.6100 area. On the downside, as long as 1.5991 key resistance holds, the rise from 1.5602 could be treated as correction of the downtrend from 1.5991, another fall towards 1.5000 is still possible.
