Date de publication : 26 avr. 2023Date de mise à jour : 28 août 2024Lecture de 2 min

To improve the transaction efficiency of liquidated futures/swaps positions, with no effect on the market liquidity, OKX develops the following methodology

1.Glossary

a.Forced-liquidation Price: When the mark price reaches the forced-liquidation price and a user’s margin is lower than the required level, force-liquidation will be triggered.

b.Bankruptcy Price: The price at which a user loses all margin

c.Entrusted Price of Liquidated Position: The price at which a liquidated position is put into the market by our forced-liquidation engine after forced-liquidation

d.Trading Price of Liquidated Position: The actual transaction price of the liquidated position in the market

2.Liquidated Futures Position Price Calculation

a.Objective:

Creating a more reasonable entrusted price, instead of using bankruptcy price, for reselling liquidated positions taking account of factors such as market depth, basis and mark price, so as to minimize market impact, and lower the systematic risk.

b.Rationale

When a position is forced-liquidated and taken over by the forced-liquidation engine, it will not be put into the market at the bankruptcy price directly. Instead, the entrusted price will be calculated based on current market depth, basis, and mark price to increase transaction efficiency and return to cover the loss.

3.Inquiry for Liquidated Positions and Margin Call Loss

a.After the price change, some positions may be transacted at lower prices than their bankruptcy prices(for closed long positions) or higher(for closed short positions). The margin call losses caused by the difference between the bankruptcy price and transaction price will be shown in the forced-liquidation list.

b.The margin call losses caused by liquidated positions after price changes will be cleared with the margin call losses from unfulfilled liquidated positions altogether. The total loss will be compensated by the insurance fund.

c.The total margin call loss can be checked on the forced-liquidation page:

= Margin call losses of fulfilled liquidated positions + Margin call losses of unfulfilled liquidated positions
