Liquidation, also known as forced closure, is a protective mechanism triggered when the value of a user's position in a particular currency falls below the minimum maintenance margin.**Basic Fields and Their Meanings**

| Maintenance Margin      | In an account's particular currency assets, this is the amount of margin for the current perpetual contract positions. There is generally a minimum requirement for the maintenance margin. If it falls below this minimum, it triggers a forced liquidation. |
| <p>Margin Ratio<br></p> | Margin Ratio = (Initial Margin + Unrealized Profit/Loss in the Position) / (Maintenance Margin Required for the Position Size + Liquidation Fees). The platform's current minimum margin ratio is 0.50%.                                                      |

1. Minimum Maintenance Margin = Position Size \* Mark Price \* Maintenance Margin Ratio + Estimated Liquidation Fees.
2. The typical maintenance margin ratio is usually around 0.50%.
3. After liquidation of a specific currency, the balance in the user's Exchange Wallet and other positions will not be affected.
