GBP/USD is approaching a crtiical point as the RSI shows it is seriously overbought now. It's fair to assume a correction will take place, once price touches the upper trendline around 1.29 level. Note: Pay attention to USD strength - the weaker the USD, the more likely for there to be a break above the upper trendline.
