Should we expect a breakout or a rebound on GBPUSD?

Past performance is not an indicator of future results.
The movement of GBPUSD towards the resistance line of a Channel Up is yet another test of the line it reached numerous times in the past. We expect this line test to happen in the next 7 hours, but it is uncertain whether it will result in a breakout through this line, or simply rebound back to current levels.
