GBP/USD Price Analysis: Technical outlook

From a daily chart perspective, the GBP/USD is upward biased as buyers gain momentum, reflected on the Relative Strength Index (RSI).  The RSI aims upwards yet with a room before turning overbought.

That said, buyers need to clear the conglomeration of technical levels, with the 1.2800 figure and a downslope resistance trendline passing around that area. Once surpassed, the next stop would be the year-to-date (YTD) high of 1.2893, which is shy of 1.2900.

On the other hand, if GBP/USD tumbles below 1.2700, that could sponsor a leg down toward the confluence of the May 3 high turned support and the 100-day moving average (DMA) at around 1.2643. Further losses lie at 1.2600.
