Margin Call: 100%
If your margin call reaches 100%, you will not be able to open further trades and will need to add more funds.
Stop Out level: 70%
If your margin reaches 70% or below, a Stop-Out will occur on your account, closing any open positions.
To keep a high margin level, you may either boost your equity by adding additional margin to your account or decrease the margin you’re trading with by reducing the lot size of your holdings.
