Actually, the situation with OK back then was pretty simple. The rules at the time didn’t limit opening positions, and you could withdraw the margin when in profit. The liquidation costs were shared by the counterparty’s profit side, with the platform covering part of it. Then the platform noticed something was off because the margin was withdrawn, and the counterparty’s liquidation price was very close. They reminded users to reduce their positions, but the users refused, so the accounts were frozen. However, the platform didn’t execute early liquidation? In the end, it directly led to liquidation. Based on the platform’s response and market analysis at the time.
