The GBPUSD had a significant bullish momentum yesterday. On h4 chart below we can see that the trendline resistance (red) has been convincingly violated to the upside. This fact show me nothing but the end of my bearish outlook and the beginning of bullish reversal scenario at least targeting 1.6468 area. CCI in overbought area and heading down on h4 chart so watch out for potential downside correction testing 1.6225. Break below that area could trigger further bearish correction towards 1.6140 but short position is not recommended.
