A Stop Out occurs when your account’s margin level falls below a certain threshold. At this point, the platform automatically closes positions to protect your account from further losses. The Stop Out level depends on your account type:
RoboMarkets CFD: 40%
MetaTrader 5 Pro: 40%
Priority of closure: In case the Account Margin Level is less or equal to the Stop Out Level, the system sends a Stop Out order(s) to close all opened deals. In the case a Stop Out order is cancelled by the execution venue and the Account Margin Level is still less or equal to Stop Out level, the system sends Stop Out order(s) again.
