Straits Futures Indonesia primarily focuses on commodities, futures, options, and forex trading. These are the main instruments available for trading on the platform. However, SFI does not offer stocks, indices, or cryptocurrencies, which could be a limitation for traders looking for a more diversified range of assets. If your interest lies specifically in trading commodities, futures, or forex, then SFI markets provide excellent opportunities. But for those interested in stocks or digital currencies, SFI may not meet all your investment needs.
