I think GBPUSD will go down soon, because in last few days GBPUSD seems exhausted to go up.
Support zone on 1.313XX is quite strong, probably GBPUSD will going up at least till 1.326XX.
GBP bearish seems exhausted and now trend has changed to bullish.
GBPUSD seems exhausted to climb. I think GBPUSD start to fall from now.
