② Violent price fluctuations may cause slippage
When the market fluctuates too fast and direct liquidation will cause significant slippage, Vault can temporarily hold positions and wait for better liquidity before closing them. This mechanism is similar to an insurance fund, and its purpose is to reduce systemic risks.

③ Systemic risk, too many liquidation orders
If the price of an asset soars or plummets, a large number of users are liquidated, and the market cannot digest all liquidation orders in a short period of time, Vault may take over multiple positions at one time and then gradually close them. Similar to the insurance fund mechanism of CEX, it prevents the market from entering a vicious cycle.
