## Portfolio Liquidation Thresholds

Portfolio liquidation thresholds are the predefined price or collateralization levels at which a trader's entire portfolio is automatically liquidated to prevent further losses to the protocol. These thresholds are designed to ensure that the protocol remains solvent by closing out under-collateralized positions before they become a liability.

In cross-margined accounts, these thresholds are particularly complex because they must account for the aggregate risk of multiple, potentially unrelated positions. If the threshold is breached, the liquidation engine takes control, selling assets to pay off debts.

Setting these thresholds correctly is a delicate balance; if they are too tight, traders are frequently liquidated during minor price fluctuations, while if they are too loose, the protocol risks insolvency during major crashes. Effective management requires constant monitoring of portfolio health and volatility.
