When the maintenance margin ratio of a futures position is ≤100%, position reduction or forced liquidation may be triggered. Liquidation does not occur all at once. The system will first reduce the position and may proceed to full liquidation if risk conditions are not met.
Before placing an order, you can use the calculator to estimate the liquidation price or assess the potential liquidation price range based on your position parameters.

Notes
The liquidation price is based on the mark price. You can switch the price type on the candlestick chart to view the mark price and its historical movements. During liquidation, standard trading fees apply, and additional liquidation-related costs may be incurred to cover execution slippage and potential losses during the liquidation process.
The forced liquidation mechanism refers to the process by which the system manages a user’s risk positions when the maintenance margin ratio of a position or account reaches a defined risk threshold. This process generally includes pre-reduction checks (order cancellation), position reduction, and forced liquidation.
The specific liquidation process may vary depending on the margin mode. For more details, please refer to the cross margin trading rules for each mode.
For futures trading, liquidation conditions are primarily determined by the maintenance margin ratio. When the maintenance margin ratio of a futures position is ≤100%, position reduction or forced liquidation may be triggered.
