The forex market trades 24 hours a day during the week. This is where you can trade the world's currencies, such as U.S. and Canadian dollars, and the Euro. Think forex is confusing? Here's what you need to know. With forex trading, consider starting with at least $500, but preferably more. The forex market offers leverage of 50:1 (this varies by broker), so a $500 deposit means you can trade and earn, or lose, on $25,000 of capital. Profits and losses mount quickly.
