How to enable cross-margin mode on Bybit? (Risk management)

Understanding Cross-Margin Mode

1. Cross-margin mode allows traders to use the entire available balance in their wallet as collateral for open positions across all contracts within the same trading pair group.

2. This mode dynamically allocates margin from the unified wallet balance, reducing the likelihood of isolated margin exhaustion on individual positions.

3. Unlike isolated margin, cross-margin does not assign fixed margin per position—instead, it shares equity across active trades to sustain them during volatility.

4. The system automatically draws from unrealized PnL and available wallet balance when margin ratio approaches liquidation thresholds.

5. Traders must recognize that losses on one position can directly impact the margin health of other positions under the same cross-margin account.

Step-by-Step Activation Process

1. Log into your Bybit account via web or mobile application using verified credentials.

2. Navigate to the Derivatives section and select either USDT or USDC perpetual contracts depending on your preference.

3. Click the gear icon located in the top-right corner of the trading interface to access contract settings.

4. Locate the Margin Mode dropdown menu and choose Cross from the available options.

5. Confirm the change by clicking Confirm; the platform will apply the new margin mode instantly without requiring position closure.

Risk Implications of Cross-Margin Usage

1. Liquidation risk becomes interconnected—sharp adverse moves across multiple positions may trigger cascading liquidations if total equity falls below maintenance margin requirements.

2. Unrealized profits contribute to margin buffer, but unrealized losses erode it immediately, increasing sensitivity to price swings.

3. Funding rate accruals and fees are deducted from the shared wallet balance, affecting net margin availability in real time.

4. Position size limits adjust dynamically based on current wallet equity, potentially restricting new entries during drawdowns.

5. Manual margin adjustments are disabled in cross-mode; users cannot add or remove margin from specific positions independently.

Monitoring Margin Health in Real Time

1. The Account Overview panel displays total wallet balance, used margin, available margin, and margin ratio in real time.

2. A red margin ratio indicator signals proximity to liquidation; values below 100% indicate insufficient collateral relative to open exposure.

3. Historical margin usage is visible under the Wallet Fund History tab, showing margin allocations, funding deductions, and PnL settlements.

4. Active positions list includes individual margin utilization percentages, enabling quick identification of high-leverage contributors to overall risk.

5. Margin call alerts can be enabled in notification settings to receive email or push warnings when margin ratio drops below user-defined thresholds.

Frequently Asked Questions

Q: Can I switch back to isolated margin after enabling cross-margin?A: Yes. Users may toggle between cross and isolated margin at any time without closing positions, though the change applies only to newly opened orders unless modified manually per position.

Q: Does cross-margin affect my spot wallet balance?A: No. Cross-margin operates exclusively within the derivatives wallet. Spot assets remain segregated and inaccessible for derivative margin unless explicitly transferred via wallet transfer function.

Q: Why does my margin ratio fluctuate even when prices are stable?A: Fluctuations occur due to funding rate payments, fee deductions, and changes in unrealized PnL—even minor price movements or time-based settlement events impact the calculation continuously.

Q: Is cross-margin available for all contract types on Bybit?A: Cross-margin is supported for USDT and USDC perpetual contracts, but not for inverse perpetuals or futures with coin-margined settlement structures.
