GBPUSD is my favorite pair. I made a huge loss in this pair. But I like it because now I am making a huge profit from this. This pair has no right direction. I changes in a high rate. It can go down or up 100 pips in a second which happened in November in last year. Maintaining a lot of strategy it is unable to measure. Only becoming a skilled trader and patient you can able to make profit long term from this pair.
