There is no doubt that forex trading can be risky. For one thing, any future outcome is not entirely predictable. Currencies change value in comparison to one another for reasons and to degrees that at times defy logic and comprehension. When real money is at stake in a forex transaction, the fact that currencies are traded on margin magnifies the rewards of being right and the penalties for being wrong. Many forex brokers, with the exception of those that comply with U.S. regulations where leverage is capped at 50:1, offer typical leverage levels around 100:1, 200:1, and in some cases as high as 500:1.
