GBP/USD faces pullback risks with signs of uptrend fatigue on technical charts.
The 4-hour chart shows the bulls have faced rejection in the 1.3750 neighborhood multiple times since Jan. 21. That, alongside lower highs on the 4-hour chart Relative Strength Index, indicates scope for a pullback.
The immediate support is seen at 1.37, which, if breached, would open the doors to 1.3610 (Jan. 26 low).
