USD continues to gain on its value supported by recent US data which indicates stability and constant raise in labour market, while GDP for the third quarter showed 5% growth, much above forecasted incline. This also points out that Fed could be raising interest rates soon, perhaps even in the first quarter of 2015, though Fed officials are still not hinting at any particular date.
Sterling is stable around 1.5550 level in a tighter-range European part of the session, with UK banks being closed in observance of Boxing Day holiday. US session should also be a steadier one as there will be no data releases. Pair is likely to find support around 1.5530 level and resistance above 1.5580 area.
