I've been using Arlington Asset Investment Corp Ltd for a while now, and it's got its strengths. The platform offers a wide range of assets for trading, which is pretty cool. The 24/7 trading access via the ST5 platform is a definite advantage, especially for someone like me who enjoys trading at odd hours. However, I've found the customer support a bit limited—primarily email-based—and wish they had more educational resources for those looking to learn more about trading. Overall, it's a decent platform with room for improvement.
