Bybit Isolated vs Cross Margin: Which One Protects You Better

Isolated Margin in Plain Terms

Isolated margin locks a fixed amount of collateral to one position. If that position is liquidated, you lose exactly what you allocated to it — no more — but you also get no help from the rest of your balance if the position needs a bit more room.

Cross Margin in Plain Terms

Cross margin uses your entire available futures balance as collateral for every open position. That can save a position from a temporary dip that isolated margin would have liquidated, but a big enough loss can draw down your whole balance, not just what you'd earmarked.

How Bybit Implements Both Modes

Isolated and cross margin, plus portfolio margin for eligible UTA accounts that nets risk across positions, and one-way and hedge mode, both selectable per symbol from the position settings.

Where This Gets Tricky on Bybit

partial liquidation on larger positions, an insurance fund, and ADL if the insurance fund can't absorb a loss.

A Reasonable Default

Isolated margin while you're still learning a pair's volatility, cross margin only once you understand exactly how much of your balance you're putting at risk by using it — and never assume the mode you used last time is still selected.

• Confirm the margin mode before every new position, not just the first one
• Isolated caps the loss but can liquidate sooner
• Cross shares risk across positions but also shares losses
