Currently, opposing positions' "Profit " calculated based on the entry price is used to determine the deleveraging priority, where the opposing positions with the highest profit will be deleveraged first. After the upgrade, the "Rate of Return" calculated based on unrealized PNL X Leverage will be used to calculate the priority ranking. What is ADL In the event of liquidation, if the liquidation order can not be filled in the market at the bankruptcy price, it will be taken over by the insurance funds. If the insurance funds can not cover the loss as well, an ADL event will occur. The ADL system will automatically deleverages opposite positions based on deleveraging priority.
