🎒Portfolio Margin and Liquidations

Hyperliquid, SYMM and Vertex work off the concept of portfolio margin.

All your positions are in portfolio margin, meaning they share unified collateral and thus you must monitor the overall account health to avoid liquidations.

There is no single 'liquidation' price on a pair, users must ensure that their 'Balance' is > 'Maintenance Margin'.

Liquidation logic

Liquidations ensue when your Cross Margin Ratio % reaches certain thresholds. The risk engine is complex but essentially you want to ensure this number stays less than 90%. To mitigate liquidation risk, deposit more to your account and/or close existing trades.

Note, we do not show an ‘estimated’ liquidation price for each trade given the path dependence of each leg it’s very inaccurate for the following reasons.

When you pair trade there are multiple different ‘paths’ to get from say a level of 100 to 90 (-10%)

Eg. Asset A could stay flat and asset B could go up 10%

or Asset A could go up 20% and asset B could go up 30%

Etc etc. So the concept of a single liquidation level for a pair is not possible as the margin requirements for each leg are different.

The most important thing is to monitor your overall account health and manage risk at a portfolio level.
