GBPUSD is testing a long term resistance trend line on its weekly chart. A clear break above the trend line resistance could see price rise towards next resistance level at 1.3950. This level would be the final destination of the bullish movement from the October 2016 low of 1.1946. Near term support level is at 1.3360. A breakdown below this level could see a reversal pullback towards the bullish support trend line on the daily chart. A clear break below this trend line could confirm that the whole upside movement from 1.1946 is complete.
