Maintenance Margin is the minimum margin required to continue holding a position.
It will increase or decrease according to the trader's selected risk limit. By default, all risk limits start at the lowest maintenance margin level inside each trading pair's risk limit table.
Liquidation occurs when the isolated margin for the position is less than its maintenance margin level.
Order Value = Contract Size x Entry Price
Maintenance Margin = Maintenance Margin Rate x Order Value
The maintenance margin rate (MMR) required for a position is based on the selected margin level requirements determined by its position value.
Example:
Trader place a long position of 1 BTC at USDT 10,000 with 50x leverage (Isolated Margin).
Initial Margin = 1 x 10,000 x 1/50 = 200 USDT
Maintenance Margin = 1 x 10,000 x 0.5% = 50 USDT
This means that this position could take an unrealized loss (Mark Price) of up to 150 USDT (200USDT – 50USDT) before liquidation takes place.
