The most popular commodities for traders are gold and oil. This is because both enjoy excellent liquidity and sources of information. However these are not necessarily the best commodities to trade. The best commodity for any trader is the one they understand the best. One where they have detailed knowledge about the market, or about supply and demand for the particular commodity. It’s this deep knowledge that makes it easier to successfully trade any commodity. And anyone can get this type of knowledge through research and study.
