Loss-cut refers to the forced cancelation of a held position as a way to prevent further losses from happening when losses exceed a certain level. In order to minimize losses caused by market fluctuations, LINE BITMAX will execute a loss-cut if your margin maintenance rate falls below 100%.
If your margin maintenance rate falls below 100%, all unfilled margin sell orders will be forcibly canceled, and your margin will be released from the restraints those orders placed on it. If your margin maintenance rate is still below 100%, all positions will be canceled at that point through a closing buy trade.
Note: There is no grace period offered for depositing more money to your margin if your margin maintenance rate falls below 100%.
