How to Use Isolated Margin vs Cross Margin on Bybit? (Margin Modes)

Understanding Isolated Margin

1. Isolated margin allocates a fixed amount of capital specifically for a single position, separating it from the rest of the account balance.

2. Traders manually set the margin size before opening a trade, and that value remains unchanged unless adjusted manually.

3. Liquidation occurs only when the isolated margin assigned to that position is fully depleted by adverse price movement.

4. This mode supports precise risk control, as losses are capped at the designated margin level regardless of overall equity fluctuations.

5. It is commonly used by experienced traders executing high-leverage strategies on specific assets without exposing their entire portfolio.

Understanding Cross Margin

1. Cross margin utilizes the entire available wallet balance as collateral for all open positions simultaneously.

2. When one position faces liquidation pressure, Bybit dynamically draws from unrealized PnL and other positions’ equity to sustain it.

3. This mode increases the effective margin buffer, delaying liquidation compared to isolated setups under identical market conditions.

4. However, a sharp drawdown in one large position may trigger cascading liquidations across multiple trades due to shared collateral.

5. It suits traders maintaining diversified portfolios with correlated instruments who prefer automatic margin sharing over manual allocation.

Switching Between Modes on Bybit

1. Users must navigate to the trading interface, click the margin mode toggle located near the order entry panel.

2. A confirmation modal appears showing current position exposure, maintenance margin requirements, and estimated liquidation prices before switching.

3. Switching from cross to isolated requires selecting an exact margin value — Bybit will not auto-assign defaults during this transition.

4. Reverting from isolated to cross margin is instant but resets all position-specific margin assignments to global wallet balance usage.

5. Active orders remain unaffected during the switch, though stop-loss and take-profit levels retain original parameters without recalibration.

Risk Implications of Each Mode

1. Isolated margin introduces clear boundary conditions: if the assigned margin hits zero, the position closes immediately at the bankruptcy price.

2. Cross margin introduces interdependence — gains in one position can offset losses in another, yet volatility spikes may drain total equity faster than anticipated.

3. Funding rate accrual continues uninterrupted in both modes, but isolated positions reflect funding impact solely against their dedicated margin base.

4. Bybit calculates maintenance margin differently per mode: isolated uses position-only metrics while cross incorporates net wallet value and open PnL.

5. Traders holding long-term positions during low liquidity periods often face higher slippage risks under cross margin due to broader equity reallocation mechanics.

Frequently Asked Questions

Q1. Can I use different margin modes for different contracts on the same Bybit account?Yes. Each linear perpetual contract allows independent margin mode selection regardless of other active instruments.

Q2. Does changing margin mode affect my unrealized PnL calculation?No. Unrealized profit or loss is computed identically in both modes using mark price and entry price — only margin utilization logic differs.

Q3. What happens to pending orders when I switch from cross to isolated margin?Pending limit, stop-market, and take-profit orders remain queued but will execute under the newly selected isolated margin rules once triggered.

Q4. Is there a fee associated with switching between margin modes?No. Bybit does not charge any fees for toggling between isolated and cross margin settings at any time.
