How to use 'Isolated Margin' on Bybit? (Risk isolation)

Understanding Isolated Margin Mechanics

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

2. Users manually set the margin value before opening a trade, and this value remains constant unless adjusted explicitly by the trader.

3. Liquidation occurs only when the position’s unrealized loss depletes the isolated margin entirely — no cross-account drawdown is possible.

4. This model prevents one losing position from affecting other open positions or the overall wallet equity.

5. Margin level is calculated as (Position Value / Isolated Margin) × 100%, and serves as the primary indicator for proximity to liquidation.

Setting Up Isolated Margin on Bybit Interface

1. Navigate to the Derivatives tab, select either USDT or USDC perpetual contracts, then choose your preferred trading pair.

2. Before placing an order, locate the margin mode toggle near the order entry panel and switch from Cross to Isolated.

3. Enter the desired margin amount in the “Margin” field — this value must be within the minimum required margin for the selected leverage and position size.

4. Confirm the trade using market, limit, or conditional order types; the system locks the specified margin immediately upon execution.

5. After opening, users can adjust the isolated margin upward or downward via the “Add Margin” or “Reduce Margin” options in the position panel.

Risk Parameters and Liquidation Triggers

1. The maintenance margin requirement varies by symbol and leverage tier — Bybit displays this dynamically based on current position parameters.

2. Liquidation price is recalculated in real time as mark price moves, and appears alongside entry price and take-profit levels in the position details section.

3. A forced liquidation initiates automatically when the margin level drops to or below 100%, meaning unrealized loss equals or exceeds the allocated isolated margin.

4. During liquidation, Bybit applies a 0.5% insurance fund fee on the position’s notional value, deducted from the isolated margin before settlement.

5. Partial liquidations do not exist under Isolated Margin — the entire position closes at once when the threshold is breached.

Adjusting Isolated Margin Post-Entry

1. Traders may increase margin to lower the liquidation price and extend breathing room during adverse price movement.

2. Reducing margin is permitted only if the resulting margin level stays above the maintenance threshold and no partial close is triggered.

3. Margin adjustments are processed instantly and reflected in updated liquidation and margin level calculations without requiring position closure.

4. Each adjustment generates a separate transaction record visible in the Account History tab under “Margin Change” entries.

5. Adjustments made during high volatility may experience slight delays due to queue processing but remain effective at the next price tick.

Frequently Asked Questions

Q: Can I switch from Isolated to Cross Margin while a position is active?Yes. Bybit allows margin mode switching for open positions, but doing so resets the margin allocation logic and may trigger immediate liquidation if the new cross-margin balance falls below maintenance requirements.

Q: Does isolated margin affect funding rate payments?No. Funding rates are calculated and applied identically regardless of margin mode — they depend solely on position size, mark price, and index price differentials.

Q: Are stop-loss orders guaranteed execution under Isolated Margin?Stop-loss orders operate as conditional market orders and are subject to slippage during gaps or low liquidity — their execution does not alter the isolated margin calculation or prevent liquidation if price breaches the liquidation level first.

Q: What happens to unused isolated margin after closing a position?The full remaining isolated margin is automatically released back into the available balance and becomes accessible for new trades or withdrawals without delay.
