Most retail investors should spend time investigating a forex dealer to find out whether it is regulated in the U.S. or the U.K. (dealers in the U.S. and U.K. have more oversight) or in a country with lax rules and oversight. It is also a good idea to find out what kind of account protections are available in case of a market crisis, or if a dealer becomes insolvent.
Challenge: Banks, brokers and dealers in the forex markets allow a high amount of leverage, which means that traders can control large positions with relatively little money of their own. Leverage in the range of 100:1 is a high ratio but not uncommon in forex. A trader must understand the use of leverage and the risks that leverage introduces in an account. Extreme amounts of leverage have led to many dealers becoming insolvent unexpectedly.
