How Liquidation Works
When you trade with leverage, you borrow funds from the exchange to amplify your position. The exchange requires you to maintain a minimum amount of collateral (maintenance margin). If your losses eat into this collateral beyond the maintenance level, the exchange forcefully closes your position — this is liquidation.
Liquidation Process:
1. Price moves against your position significantly 2. Margin ratio drops below maintenance margin requirement 3. Exchange's liquidation engine activates automatically 4. Position is closed at the current market price 5. Remaining collateral (if any) is returned minus liquidation fees
Calculating Liquidation Price
For a long position: Liquidation Price = Entry Price × (1 - 1/Leverage + Maintenance Margin Rate)
For a short position: Liquidation Price = Entry Price × (1 + 1/Leverage - Maintenance Margin Rate)
Example:
- Entry price: $50,000 (BTC)
- Leverage: 10x
- Maintenance margin: 0.5%
- Long liquidation price ≈ $45,250 (roughly 9.5% below entry)
Partial vs Full Liquidation
Some exchanges use partial liquidation to reduce your position size instead of closing it entirely. This can help you maintain a portion of your trade:
- Binance: Uses multi-tier liquidation, reducing position incrementally
- Bybit: Partial liquidation engine reduces position to lower risk
- Kraken: Full liquidation at maintenance margin level
Liquidation Fees
Most exchanges charge a liquidation fee, typically 0.5% to 1.5% of the position value. This fee is deducted from your remaining collateral.
How to Avoid Liquidation
- Use lower leverage — 3-5x instead of 50-100x
- Set stop-loss orders well above your liquidation price
- Add margin to your position when it moves against you
- Use isolated margin to limit losses to that position only
- Monitor your margin ratio and act before it's too late
Insurance Funds and ADL
Exchanges maintain insurance funds to cover losses when liquidated traders' positions can't be closed at a favorable price. If the insurance fund is depleted, Auto-Deleveraging (ADL) may occur, where profitable traders' positions are automatically reduced.
