Forex trading as it relates to retail traders (like you and I) is the speculation on the price of one currency against another. For example, if you think the euro is going to rise against the U.S. dollar, you can buy the EURUSD currency pair low and then (hopefully) sell it at a higher price to make a profit.
The ability of the forex to trade over a 24-hour period is due in part to different time zones and the fact it is comprised of a network of computers, rather than any one physical exchange that closes at a particular time.
