As shown in 4 hour chart of GBPUSD
, its trading in sharp upper bound range since May 2015 . Most of all technical traders use support and resistance
to execute their trades, But I believe that news gives a force to break support or resistance. Even in strong trend it gives pullback for the price to trade within proper R/R. Today's strong Q2 GDP number gave force to broke upper trend line
chart . Now waiting for Revised GDP numbers of British Pound on Friday-AUG 28th 2015 .
