Aiko Markets margin rules: 

Margin Call: 100%

Stop Out Level: 144%

When reaching 100%, you will get a margin call and you will be restricted from opening any trades. If you reach 144% margin or below, a Stop-Out will occur. Your TradeLocker will start closing your open trades one by one.

You may either boost your equity by adding more margin to your account or decrease the margin you're trading on by reducing the lot size of your trades to preserve your high margin levels.
