GBPUSD: weekly volatility outlook. Oct 25th-28th 2011
Last week the currency pair continued its rally. On Oct 17th there was no major news, so GBPUSD was traded around 38.2 % of the 1.6617 - 1. 5272 downswing. Tuesday’s CPI decline made the British Pound lose a bit of its value against the US Dollar. GBPUSD reached the option barrier 1.5635, which later turned into the level of support.
