GBPUSD has seen a continuous downtrend with no significant pullbacks. However, it is losing downwards momentum in synchrony with USD's loss of upwards momentum. This week or early next week, GBPUSD should be expected to enter a significant retrace. Further, minor retraces in the current downtrend are aligned for harmonic Fibonacci levels, which can be used to estimate a price target. This is a risky trade, as it attempts to catch a pullback rather than enter the trend from a pullback.
