Forex stands for foreign
exchange. Sometimes its also called FX.
A simple
way to understand the foreign exchange market is to think of it as changing
money when you travel abroad. When you alter money, you sell money and buy
another at the current exchange rate. This is because the worth of your own
money is not equal to the worth of the money you require to buy. In effect, you
have traded money and this is similar to foreign exchange trading.
