The History of the foreign exchange market is quite a long and illustrious one that goes back all the way to the time of barter trade. Perhaps the most important event in recent  forex strategies  was the introduction of the euro as a single currency by the European Union.  The EU adoption has greatly simplified trade in Western Europe and has in turn made the economy in the region more stable.

Great Britain is one such country that has not adopted the euro and still uses its own currency, the British Pound for commerce within the country.
