Margin, Leverage & Positions
What's the difference between cross and isolated margin?
Cross margin backs every position with your full account collateral, sharing PnL and margin - a winning position in your account can offset a losing position, and liquidation happens only when total equity falls below combined maintenance margin.
Isolated margin allocates a fixed amount to one position: losses can’t exceed it, but profits elsewhere can’t rescue it. Cross is more capital-efficient; isolated is more contained.
Arcus runs cross-only at launch; isolated margin is planned.
