GBP/USD holds above 1.2660-1.2650, where the 200-period Simple Moving Average (SMA) on the 4-hour chart and the Fibonacci 23.6% retracement level of the long-term uptrend align. In the meantime, the Relative Strength Index (RSI) rises toward 60, reflecting a buildup of bullish momentum.
On the upside, 1.2700 (psychological level, static level) could be seen as next hurdle before 1.2760 (static level) and 1.2800 (psychological level, static level).
If GBP/USD returns below 1.2660-1.2650 area and starts using it as resistance, additional losses toward 1.2620 (100-period SMA, 50-period SMA) and 1.2600 (psychological level) could be seen.
