Calculation of Maintenance Margin
Updated at:154 days 17 hours ago

Maintenance Margin is the minimum margin required to continue holding a position.

Maintenance Margin is affected by the position value and the maintenance margin ratio.

Position Maintenance Margin = ( Value Position * MMR ) + Close Position Fee

The maintenance margin ratio is normally half of the reciprocal of MMR.

For example, BTC_USD supports 50X leverage at maximum, that the MMR is 0.5%.

*Note: the MMR is affected by the risk limit.

For example:

A user opens a 100USDT worth of long position with 100X BTC_USDT,

then the Maintenance Margin of this user's position is:

( Position Value*MMR ) + Close Position Fee which is: (100*0.5% )+ 100*0.075% = 0.57USDT

The Initial Margin is:

(100/100)+100*0.075% = 1.075USDT

So the possible loss of this position is ( 1.075-0.575 ) = 0.5USDT at maximum,

the position will face a forced liquidation when the margin is insufficient to maintain the position and the margin.
