What is isolated vs cross margin on Bybit? A Bybit margin trading tutorial.

Understanding Margin Types on Bybit

Bybit offers two primary margin modes for traders engaging in perpetual and futures contracts: isolated margin and cross margin. These modes determine how much capital is allocated to a specific position and how liquidation risks are managed. Traders must select one of these modes before opening a position, as the choice significantly impacts risk exposure and potential returns.

Isolated Margin Mode Explained

In isolated margin mode, traders manually set the amount of margin assigned to a particular position. This designated margin acts as the sole collateral for that trade. Any changes to the margin must be done manually by the user, either increasing or decreasing it based on market conditions or strategy adjustments.

1. The margin is 'isolated' from the rest of the account balance, meaning only the allocated amount is at risk.
2. Liquidation occurs when the position’s losses exceed the isolated margin, protecting the rest of the account funds.
3. Traders have full control over leverage, which can be adjusted within allowed limits for each contract.
4. Ideal for those who want precise risk management on individual trades without affecting other open positions.
5. Requires active monitoring since automatic margin top-ups do not occur under this mode.

Cross Margin Mode Explained

Cross margin uses the entire available balance in the account’s wallet as collateral for all open positions. The system automatically allocates equity across multiple trades, reducing the chance of liquidation due to broader support from the total balance.

1. All positions share the account’s available balance as margin, enhancing buffer against sudden price swings.
2. Leverage is applied dynamically based on total equity and unrealized P&L across positions.
3. Offers higher resistance to liquidation compared to isolated margin under volatile conditions.
4. Less manual intervention required, making it suitable for less experienced traders or those managing multiple positions.
5. Risk is spread across the whole portfolio, so a sharp move against any position can affect overall account health.

Key Differences Between Isolated and Cross Margin

The decision between isolated and cross margin hinges on trading style, risk tolerance, and level of involvement desired in managing open trades.

1. Isolated margin limits risk per trade but demands active oversight, while cross margin provides automatic support from the total balance.
2. In isolated mode, leverage is fixed per position; in cross mode, effective leverage varies with account equity fluctuations.
3. Isolated margin allows fine-tuning of risk allocation, whereas cross margin simplifies management across complex portfolios.
4. A losing position in cross margin can consume equity meant for other trades, potentially triggering cascading liquidations during extreme volatility.
5. Traders using high-leverage strategies often prefer isolated margin to contain losses, avoiding total account wipeouts.

Frequently Asked Questions

Q: Can I switch between isolated and cross margin after opening a position?A: No, once a position is opened under one margin mode, it cannot be switched. Traders must close the current position and reopen it under the desired mode.

Q: Does cross margin always prevent liquidation better than isolated margin?A: Not necessarily. While cross margin uses more funds as collateral, severe market moves can still lead to liquidation. It delays the point of liquidation but doesn’t eliminate the risk.

Q: How is leverage affected in cross margin mode?A: Leverage in cross margin isn't fixed. The system adjusts the effective leverage based on total account equity and unrealized gains or losses across all positions.

Q: What happens to my other positions if one is liquidated under cross margin?A: The liquidation of one position reduces the overall equity in the account, which may impact the margin available for other positions, especially during rapid price movements.
