Liquidation is a critical concept for any trader using leverage. This guide breaks down how the liquidation price is calculated on major trading platforms. Understanding this mechanism is fundamental to managing risk effectively in volatile markets.
What is a Liquidation Price?
In leveraged trading, you borrow funds to open a position larger than your initial capital, known as margin. The liquidation price is the specific price level at which your position is automatically closed by the platform. This occurs when your losses approach the value of your initial margin, meaning you can no longer cover the potential losses on the borrowed funds. It is a risk management mechanism that protects the platform from excessive losses.
How is the Liquidation Price Calculated?
The exact formula for calculating liquidation price varies depending on the type of contract (e.g., cross margin vs. isolated margin) and the leverage used. However, the core principle remains the same across different modes.
Key Variables in the Calculation:
- Entry Price: The price at which you opened your position.
- Leverage: The multiple of your initial capital you are trading with (e.g., 10x, 20x).
- Position Size: The total value of your open position.
- Maintenance Margin Rate (MMR): This is a percentage set by the exchange, representing the minimum amount of equity (as a percentage of your position's value) you must maintain to keep your position open. If your equity falls below this level, liquidation is triggered.
General Calculation Concept:
A simplified way to think about the liquidation price for a long position is:
Liquidation Price ≈ Entry Price × (1 - (1 / Leverage) + Maintenance Margin Rate)
This formula illustrates that higher leverage leads to a liquidation price much closer to your entry price, making your position riskier. Most platforms provide built-in calculators that automatically compute this price based on your inputs before you confirm an order.

The Importance of Understanding Liquidation
Knowing your liquidation price is not just a technicality; it's the cornerstone of survival in leveraged trading.
- Risk Management: It allows you to quantify your maximum potential loss on a trade before you even enter it.
- Strategic Planning: You can set stop-loss orders at levels before your liquidation price to exit a trade on your own terms, rather than being forced out by the system.
- Preventing Margin Calls: By monitoring your distance to liquidation, you can add more funds to your margin (top up) if the market moves against you, helping to avoid automatic closure.
Strategies to Avoid Liquidation
While liquidation is a built-in feature, there are several strategies traders employ to mitigate the risk.
- Use Lower Leverage: This is the most effective way to move your liquidation price further away from your entry price. Lower leverage equals a higher tolerance for market volatility.
- Employ Stop-Loss Orders: Set a stop-loss order at a predetermined price level that you are comfortable with. This allows you to control your exit and preserve remaining capital.
- Monitor Positions Actively: Volatile markets can move quickly. Active monitoring allows you to react to adverse price movements before they reach the critical liquidation level.
- Avoid Over-Leveraging: Using the maximum available leverage on a large position is extremely high-risk. It leaves very little room for error.
Frequently Asked Questions
What happens immediately after liquidation?
When your position is liquidated, the exchange automatically closes it using the current market price. The funds used for your initial margin are first used to cover the losses. If the liquidation price is unfavorable and losses exceed your margin, you may be liable for the additional deficit, depending on the platform's risk insurance fund and policies.
Can I change my liquidation price after opening a position?
Yes, you can indirectly affect your liquidation price. By adding more funds to your margin account (increasing your collateral), you lower your leverage and push the liquidation price further away from the current market price. Conversely, taking profit or closing part of your position also changes the calculation.
Is the liquidation price the same for long and short positions?
The principle is the same, but the calculation is opposite. For a short position, the liquidation price is above your entry price. The market must rise (not fall) for your short position to be at a loss and risk liquidation.
Do different cryptocurrencies have different maintenance margin rates?
Yes. More volatile assets typically have a higher Maintenance Margin Rate (MMR) set by the exchange. This is because the potential for rapid price swings is greater, requiring a larger buffer to protect the platform from instant, significant losses.
Why did I get liquidated before reaching the shown price?
This can occur during periods of extreme market volatility or low liquidity. If the price "gaps" down (or up for a short) and skips directly past your liquidation price, the order is filled at the next available price, which may be worse. This is known as slippage.
What is a bankruptcy price?
The bankruptcy price is the price at which your initial margin is completely depleted. The liquidation process is designed to trigger before this point, ideally leaving a small amount of margin remaining. The difference between the liquidation price and the bankruptcy price is the buffer that the platform's risk system uses.
