When does the Stop Out apply?
Positions are closed on Stop Out when the Margin level drops below 20% (the position with the highest loss is closed regardless of its size, considering the largest loss at that moment). This is intended to protect both the Client and the Broker from entering a negative balance.
How to avoid Stop Out?
Reduce the size of opened positions to maintain a high level of Margin security.
You can also deposit funds into your account to increase the available Margin.
