What are the benefits of having a margin account?
Margin accounts allow you to take advantage of market opportunities and potentially increase your investment returns. With a margin account, you can borrow against your investments, giving your trades greater buying power to go long or short. It is important to note that while it can potentially lead to higher returns, it can also elevate the potential for higher losses.
With our online trading platforms, you can make intraday margin trades using real-time buying power calculations, allowing you to optimize your trades for price movements.
Margin rates vary based on the type of financial product and maturity date. Learn more about our Margin Rates.
