When you decide to trade trade Pairs not currencies per se. A very lucrative pairing at the moment is the Euro and the U.S. Dollar. They fluctuate daily and depending on the drivers –e.g the price of oil or bank closures etc the movement can be very significant. Other Pairs to consider might be the U.S.Dollar and the U.K.Pound, the U.K. Pound and the Euro. The Yen and the U.S. Dollar might also be considered.
