Traders long this market, however, face considerable resistance at the 1.23 handle, a daily channel resistance (taken from the high 1.3176) and weekly resistance at 1.2329. The main catalyst behind the latest run higher comes on the back of prospects of a Brexit-deal breakthrough. Consider staying bullish above 1.2245 in GBP/USD with a target of 1.2290 and 1.2330.
