A fan complained to me that he clearly made a profit of 4U when closing the position, but it showed he lost 8U.

What’s going on? I understood the situation and asked him to take a screenshot of his transaction history. At a glance, it was clear that he indeed made a profit of 4U, but the total fees deducted were close to 13U. So when you do the math, he indeed lost 8U. High leverage leads to high fees, so anyone who thinks it’s expensive can use my link to open an account and get rebates. Over the course of a year, you can save a lot!!!
