It is now threatening to break below this week's rising trendline as well. The RSI is cracking 40 and if it clearly breaks it, it reflects loss of this week's bullish momentum. The first level to monitor is the 1.5075-1.51 area. If the GBP/USD were to remain bullish, this area should hold as support. A break below 1.5050 puts the focus on the price bottom from the end of last week, with the low at 1.4950.
