Many CFD & forex brokers that offer stock trading also offer CFDs based on metals for their clients to trade. Although most brokers and traders limit themselves to the popular precious metals gold and silver, some brokers also offer other metals like aluminum, copper, platinum, and palladium. As always, however, the lowest spreads can be found on the most traded assets. Among all the metals, gold is by far the most traded one.
A great benefit with trading gold and other metals as CFDs rather than directly as futures contracts is that it is much easier to meet the margin requirements that most CFD brokers set. This way, even ordinary traders with small accounts can get access to high leverage and make large trades in the gold market. And since gold is known to be such a stable asset, large positions are often necessary in order to get meaningful profits.
