What is a forced liquidation?
Forced liquidation, also known as liquidation. When your margin cannot meet the maintenance margin requirement of a position, a forced liquidation will be triggered and all the margin used for the position will be lost. When the mark price reaches the liquidation price, the liquidation will be triggered.
When will I be forced to close out?
When a forced liquidation is executed, all current entrusted orders in the account will be cancelled immediately. According to the risk level of the user's position, perform forced liquidation operations of different degrees to avoid all positions being forced to liquidate. Liquidation will also charge a "liquidation liquidation fee". Therefore, we strongly recommend that users close their positions by themselves before the available assets in the account drop to the liquidation price to avoid additional fees due to forced liquidation.
When (liquidation price - opening price) / opening price * contract value ≤ maintenance margin, it is a forced liquidation.
How to calculate the liquidation liquidation fee?
You can refer to the liquidation rate of each contract in the trading rules.
