When trading commodities, it's also important to understand how to analyze them. This is due to differences in analysis, for example, between oil and gold. Gold analysis is typically based on global sentiment, inflation rates, interest rates, and the performance of the US Dollar Index. Oil analysis, on the other hand, typically relates to oil stockpile data releases, OPEC+ decisions, economic growth rates, and supply and demand. When trading commodities online, choosing a broker with low spreads offers additional benefits in terms of transaction costs.
