OTC provides a range of financial instruments for trading, including equity, derivatives, commodities, mutual funds, IPOs, and currency. These instruments provide traders with various opportunities for diversification and market exposure. However, OTC does not offer trading in stocks, cryptocurrencies, ETFs, bonds, or options, which limits the options available to some traders. If you're looking to trade a broader range of instruments, OTC may not meet your needs. Be sure to understand the instruments available when using the OTC trading platform.
