FX is the shortened term used for ‘Foreign Exchange’, the buying and selling currencies. The foreign exchange market is the biggest and most liquid financial market in the world, and operates 24/5. Almost every financial service deal across the global includes an FX transaction. On the exchange market you can trade the most popular FX pairs such as the euro/dollar, or opt for a more specialist currency. Trading reacts to both fundamentals (market news) and technical (trends), making this a dynamic asset class.
