Definition
Liquidation in the context of crypto futures trading refers to the mandatory closing of a trader's open position by the exchange when their margin is insufficient to cover potential losses, specifically when the **Margin Ratio** falls below the exchange's required maintenance margin level. This mechanism is designed to protect the exchange and the clearing house from insolvency due to a trader's negative account balance.
Why it matters
The liquidation process is fundamental to the operation of leveraged trading. Without it, traders using high leverage could potentially lose more money than they deposited, creating counterparty risk for the exchange. Liquidation ensures that losses are contained to the trader's deposited margin, maintaining the solvency of the derivatives market. Understanding liquidation is crucial for risk management, as it represents the maximum potential loss on a leveraged position.
How it works
The process is triggered when the trader's Unrealized PnL (Profit and Loss) causes the account's equity to drop to the **Maintenance Margin** requirement.
Margin Levels
A position requires initial margin to open. As market prices move against the trader, the equity decreases. The key thresholds are:
- Initial Margin (IM): The amount required to open the position.
- Maintenance Margin (MM): The minimum equity required to keep the position open.
- Margin Ratio / Margin Level: The metric used by exchanges to monitor the health of the margin account. When this ratio drops to a specific threshold (often 1.0 or lower, depending on the exchange), liquidation is imminent.
The Liquidation Engine
When the Margin Ratio breaches the liquidation threshold, the exchange's automated liquidation engine takes over. 1. **Partial Liquidation**: Some exchanges attempt to reduce the position size by closing portions of the trade to bring the Margin Ratio back above the maintenance level. This is often done if the trader has sufficient remaining margin to cover the reduced position. 2. **Full Liquidation**: If reducing the position size is insufficient or if the exchange policy dictates immediate closure, the entire position is closed at the prevailing market price. 3. **Liquidation Price**: This is the theoretical price at which the margin runs out and the position is automatically closed. Traders must monitor their distance from this price.
Liquidation Fees and Insurance Fund
When a position is liquidated, a liquidation fee is typically charged, which compensates the liquidator (often an automated system or third-party entity). If the position is closed at a price worse than the bankruptcy price (i.e., the market moves too fast), resulting in a deficit, this loss is covered by the exchange's Insurance Fund. If the Insurance Fund cannot cover the deficit, other traders may experience a process known as Auto-Deleveraging (ADL).
Practical examples
Consider a trader opening a long perpetual contract position on Bitcoin with 10x leverage.
- Initial Margin required: 10% of the notional value.
- If the price of Bitcoin drops by 10%, the position loses 100% of the initial margin (10% loss * 10x leverage = 100% loss of margin).
- At this point, the trader hits the liquidation price, and the exchange automatically closes the position to prevent the account balance from going negative. The trader loses their entire initial margin deposited for that specific trade.
Common mistakes
- **Ignoring Margin Utilization**: Traders often focus only on the entry price and neglect how much margin they are using relative to their total available equity. High margin utilization increases proximity to the liquidation price.
- **Not Accounting for Fees**: Trading fees and funding rates can slowly erode margin, bringing a position closer to liquidation than anticipated.
- **Trading During High Volatility**: Rapid price movements, common during major news events, can cause the market to skip the calculated liquidation price entirely, leading to immediate closure with potentially higher losses than expected.
Safety and Risk Notes
Liquidation is a risk mitigation tool for the exchange, but a catastrophic event for the trader. To mitigate liquidation risk:
- Use lower Leverage Ratios.
- Employ Stop-Loss Orders placed significantly below the calculated liquidation price.
- Monitor the Margin Ratio in real-time rather than relying solely on the liquidation price displayed upon entry.
- Ensure sufficient **Free Margin** is available to add collateral if the market moves adversely, thereby increasing the distance from the maintenance margin threshold.
