My friends and I, a total of five people, traded together on this platform and all experienced margin calls. They quit, but I continued and made several deposits, each resulting in a margin call. During my last attempt, despite being cautious and careful, the platform froze, there was slippage, and even attempts to lock were unsuccessful, leading to an immediate margin call. My account number is 627073, and I lost 12582.15 USD in just one order.
