Liquidation

The maintenance margin is the minimum margin required to keep the position open and not liquidated. The position will be liquidated if its margin falls below the maintenance margin.

Maintenance leverage is the maximum effective leverage that the position leverage can reach. The position will be liquidated if its leverage exceeds the maintenance leverage.

Maintenance Margin (MM) = IndexPrice * Position Value * MMR%

Pool type	Lever	MMR%
Aggregated Pool	2-21x	20%
	22x-30x	21%-29%
	31x-43x	30%-39%
	44x-50x	40%-45%
Isolated Pools	2-100x	30%

MMR% is system parameters, which will be changed later through governance.

Liquidation Fee Sequence

The sequence of fees deducted during liquidation varies between the aggregate pool and the isolated pool, designed for risk control and to reduce the cost for users to open positions.

Aggregate Pool Liquidation Fee Sequence:

Trading Fee → Executor Fee → LP Earnings

• The trading fee is the base of protocol income and is prioritized for collection. See details on protocol revenue.

• Executor fees are paid to the main chain for gas, which are unavoidable. See details on executor.

• LP earnings include funding fees and losses from user positions. See details on funding rate.

It's important to note that in extreme market conditions leading to a situation where losses exceed the margin (liquidation), priority is given to the collection of trading fees and executor fees, and it cannot be guaranteed that LPs will receive full earnings.

Isolated Pool Liquidation Fee Sequence:

Trading Fee → LP Earnings → Executor Fee

• The trading fee is the foundation of protocol income, prioritized for collection. See details on protocol revenue.

• LP earnings include funding fees and losses from user positions. See details on funding rate.

• Executor fees are paid to the main chain for gas, which are unavoidable. See details on executor.

In the event of a liquidation caused by extreme market conditions in the isolated pool, it's also not guaranteed that LPs will receive full earnings. However, all remaining assets after trading fees are deducted will be allocated to LPs, with the protocol bearing the cost of the executor.
