Trading metals is popular among traders, and it is something nearly all forex brokers offer. The focus is naturally then on precious metals, with gold and silver being the most popular. However, an increasing number of traders are also interested in taking advantage of the long-term trends that often form in the platinum and palladium markets.
Since gold is the most commonly traded metal, this is where the tightest spreads are found. The most cost-conscious traders will therefore largely stick with this metal, and avoid the other and less popular metals. History has also shown that metals, and in particular gold, performs quite well over time compared to other major assets like currencies and stocks. To this day, metals continue to be popular as a way to protect wealth against depreciation in fiat currencies.
