The GBP/USD has broken above the major resistance at 1.31450, forming a well-defined bullish channel that has been guiding the price steadily upward. The upper boundary of this channel has acted as a strong resistance, and there is a possibility of a short-term pullback as the price approaches this level. This potential reversal could lead to a retest of the previous resistance. It's important to closely monitor how the price reacts to both the resistance level and the channel boundaries to make informed trading decisions.
