What Is Maintenance Margin?
Maintenance margin is the amount of account equity required to avoid a margin call. If your equity falls below the maintenance margin, your positions will be liquidated in order to pay back the Kraken Margin Pool assets that have been used to open your margin position.
When your margin level is between 40-80%, liquidation is at Kraken’s discretion and all or a portion of your account may be liquidated; you may receive, but are not guaranteed, a margin call email.
When your margin level reaches 40% or lower, liquidation is certain. The liquidation process is automatic, and once initiated cannot be stopped.
