Cross Margin vs Isolated Margin Explained

When you open a leveraged perp position, your margin mode decides what collateral can be used to support the trade. That choice can matter as much as your leverage.

Cross margin and isolated margin are not just interface settings. They define whether risk is pooled across your account or contained to one position — and that difference rewrites your liquidation profile entirely.

The Core Difference

Isolated margin assigns collateral to a specific position. If that position goes badly, the loss is generally limited to the margin allocated to that position.

Cross margin uses a shared collateral pool across eligible positions. Profits, losses, and available account equity can support multiple positions at once.

Same market. Same entry. Same leverage. Same direction. Different margin mode → different liquidation profile.

Isolated Margin · Defined Position Risk

With isolated margin, you decide how much collateral to commit to one trade.

If ETH moves far enough against you, the position can be liquidated and the assigned isolated margin is at risk. Your remaining account balance is not supposed to directly support that position unless you manually add more margin.

That makes isolated margin useful when you want a clear risk boundary.

Cross Margin · Shared Collateral

With cross margin, eligible positions share account-level collateral. The same $5,000 account backing the same $5,000 ETH long has access to the full pool — so the liquidation price moves further away.

That extra room is useful — but it comes with a tradeoff. If ETH keeps falling, the loss can consume collateral that was backing the rest of your account.

Cross margin can make liquidation less likely on one position, but more damaging if account-level risk is not controlled.

Why Liquidation Price Changes

Liquidation depends on equity, maintenance margin, mark price, fees, funding, and margin mode. The mode is what changes which equity number the engine looks at.

The practical difference: isolated margin trades more frequent position-level liquidations for a smaller blast radius. Cross margin does the opposite.

When Isolated Margin Makes Sense

For many traders, isolated margin is the cleaner default because it forces every position to stand on its own.

When Cross Margin Makes Sense

Cross margin is not automatically more advanced. It is less forgiving if you ignore the full account.

Multi-Venue Margin Can Vary

Can You Switch Margin Modes?

This depends on the platform and the venue. Some platforms let you switch margin mode before opening a position but restrict changes afterward. Others let you adjust margin on an open isolated position, change leverage settings, or remove margin if requirements remain satisfied.

Do not assume you can always convert a live position from isolated to cross or back again. Check before entry — especially for large or event-driven trades.
