is the minimum margin required to continue holding a position.
is affected by the position value and the maintenance margin ratio.
Margin = ( Value Position * MMR ) + Close Position Fee
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.
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.
