After have made a false break at 1.5160 and has respected its trendline in 4h, GBP is making a break from their last high; so I recommend making a buy immediately until 1.5285 (EMA 150), then wait for confirmation breaking that level until 1.5300
For the opening of the London market we will have a strong Euro as it has shown in recent days due the uptrend break and still give us signals to trend upward in 4h. We should wait to take long positions as long it breaks the 50% Fibonacci til the first resistance at 1.4500 and wait confirmation for the next level at 1.5500
