there is tips in Margin order

Margin order will execute automatically when the highest bid falls below the call price and is within 10% of the 24h moving average.The call price is the price at which 75% of your collateral is required to buy back the USD owed. When your position is called your collateral will be used to buy BitUSD and if there is any collateral remaining after the short position is fully covered then 95% wiil be returned to the short，the remaining 5% will be kept by the network as fees.
