GBPUSD has retraced back into the 4H swing low, it's more likely to see continuation longs. It is preferable to wait for smaller timeframes to align first.
4H seemed to be coming off a previous supply, and the 4h swing just broke the high, so it looks more likely we will get a pullback. 4H internal structure or M15 swing structure has also changed bearish. All of this supports that we should get a pullback before the higher timeframe continuation long
