Forex trading is becoming more popular as time goes by. Perhaps you have heard of forex trading, or heard things such as "the dollar fell sharply against the yen". Not sure what all this means? Here is a basic overview of forex trading.
The foreign currency exchange market (forex) is the largest market in the world. Much larger than the stock market! Some of the reasons for its popularity are that leverage allows maximum usage for your money and there is very high liquidity. The forex market is also open 24 hours a day, although some hours are much better trading times than others.
