When does a margin call and stop-out occur?

A margin call occurs when your Margin Level falls below 80%. This is a warning that your margin level is too low to maintain your current open positions, and you are required to deposit more funds or close some positions to avoid further action from stop-out.

A stop-out occurs when your Margin Level falls even further at 50%. At this point, system will start closing from the largest floating loss until the margin level is restored to above 50% to prevent further losses and protect your capital.
