Although the stock market gets all the publicity, trading currencies in the Forex market is a little different than trading a regular company's stock.
The Forex market trades currency and trading goes on for 24 hours during 5.5 days-a-week. These hours of operation mean that the Forex market trades in 1 day what Wall St. trades in a month. Right now the US dollar is not as strong as it used to be. How stable the country is and how well tourism is going are some deciding factors for the value of a country's currency. Obviously because of a bad recession our dollar value isn't looking too good.
The Forex market can be a bit simpler than Wall St because of a limited number of popularly traded currencies. That, combined with commission free trading, creates a unique, one-of-a-kind exchange experience. Forex infographic “Forex. Explained.” by CMS Forex
