# Risk & Liquidation

Perpetual trading is leveraged, so understanding liquidation is essential. This section explains what triggers liquidation, how the mark price and cross-margin model affect it, what auto-deleveraging (ADL) is, and how to keep your account safe.

{% hint style="warning" %}
Liquidation closes your position automatically when your account can no longer meet maintenance margin. You can never lose more than your deposited balance — Yellow\.pro does not issue margin calls for additional funds.
{% endhint %}
