# Can I switch margin modes mid-position?

Isolated margin isn't available at launch (cross-only), so there's no mode switch yet.

When isolated ships in a later release, switching cross→isolated will ringfence a specified amount of collateral and isolated→cross will release it back into the shared pool.
