GBPUSD stays in a rising price channel on its 4-hour chart and remains in the uptrend from 1.3204. As long as the price is in the channel, the upside movement could be expected to continue and next target would be at 1.3500 area. On the downside, a breakdown below the bottom of the channel would indicate that the upside movement is complete, then another fall towards 1.3000 could be seen.
