Forced liquidation of contracts

Key Features of Forced Liquidation

Forced liquidation occurs when a position is automatically closed as soon as the margin balance reaches the maintenance margin level, resulting in the loss of all maintenance margin. The system initiates forced liquidation when the fair price hits the liquidation price.

Fair prices are used as the benchmark for forced liquidation. This approach helps prevent unfair liquidations caused by illiquidity or market manipulation. By using fair pricing, the platform ensures a more transparent and equitable liquidation mechanism.

Risk limits require higher margin levels for larger positions. When a large contract position is force-liquidated, it may be difficult to liquidate safely and could impact the overall market. To address this, the liquidation engine utilizes additional margin to effectively handle large positions.

Upon triggering forced liquidation, all open orders for the affected contract are canceled and margin is released to maintain the position. Orders for other contracts remain unaffected. The platform employs partial liquidation, automatically reducing maintenance margin requirements to help prevent total liquidation of all positions.

How to Calculate the Liquidation Price

The following are real calculation examples for determining liquidation prices (excluding factors such as fees).

Liquidation condition: Position Margin + Unrealized P&L ≤ Maintenance Margin

Long Position: Liquidation Price = (Maintenance Margin - Position Margin + Entry Price × Quantity) / Quantity

Short Position: Liquidation Price = (Entry Price × Quantity - Maintenance Margin + Position Margin) / Quantity

Example Calculation

Suppose you buy a BTCUSDT contract for 0.1 BTC at 50,000 USDT, with 25x initial leverage and a long position:

Maintenance Margin = 50,000 × 0.1 × 0.4% = 20 USDT

Position Margin = 50,000 × 0.1 / 25 = 200 USDT

Long Position Liquidation Price = (20 - 200 + 50,000 × 0.1) / 0.1 = 48,200 USDT

According to this formula, forced liquidation will occur if the price drops to 48,200 USDT. Traders should monitor this price closely and apply sound risk management strategies.

Liquidation Price in Different Margin Modes

In Isolated Margin Mode, the formulas above apply for calculating the liquidation price. Here, position margin refers to the isolated margin amount, and users can manually add margin to mitigate risk. Because each position is managed independently, losses in one isolated position do not affect others.

In Cross Margin Mode, all available account balances serve as position margin. However, note that in Cross Margin Mode, any available balance lost is not used as margin for other cross positions. In this mode, the account’s entire balance acts as a single unified margin pool.

Manually increasing position margin widens the gap between the liquidation price and entry price. When user risk is elevated, adding margin helps reduce the likelihood of liquidation. Additional margin also increases resilience to market volatility, creating a safer trading environment.

Risk Limits

Contract trading platforms enforce risk limits on trading accounts to reduce the risk of large-scale forced liquidations. As position sizes grow, the requirements for maintenance and initial margin also increase. Margin rates rise or fall depending on the risk limit adjustments.

The risk limit system is designed to preserve market stability and prevent systemic risk from excessive leverage. Higher margin requirements for large traders support the overall health of the marketplace.

Users can review and adjust risk limits on the trading platform as needed. Regularly reassessing risk settings is recommended as part of a sound risk management strategy.

Summary

When trading contracts, always keep an eye on liquidation price fluctuations and add margin promptly to avoid unnecessary losses from forced liquidation. Leverage trading offers the potential for high returns but also involves significant risks.

Implement robust risk management strategies and maintain position sizes appropriate for your risk tolerance. Always ensure adequate margin to handle sudden market swings, and utilize risk management tools such as stop-loss orders.

FAQ

What Is Forced Liquidation in Contracts?

Forced liquidation in contracts occurs when a trader’s margin is insufficient to maintain a position, prompting the exchange to close the position automatically. This process limits losses and maintains market stability. Positions may be closed either partially or entirely.

What Is the Legal Basis for Forced Liquidation in Contracts?

Forced liquidation is executed based on Articles 541 and 542 of the Civil Code. If specific events arise—such as default, bankruptcy filings, or payment suspension—forced liquidation is carried out immediately without notice, as stipulated by contract termination or loss-of-benefit clauses.

What Are the Procedures for Forced Liquidation in Contracts?

During forced liquidation, a liquidator is appointed and creditors are notified. Assets are then liquidated to recover claims. The procedure includes public announcement, asset sale to repay debts, and formal completion of the process.

What Are the Risks and Impacts of Forced Liquidation in Contracts?

Forced liquidation is triggered when margin requirements are not met and the exchange closes positions automatically. Using leverage can result in sizable losses. Investors may lose most of their principal, highlighting the importance of solid risk management.

How Can Forced Liquidation in Contracts Be Avoided or Delayed?

Making use of collateral or netting clauses and clearly defining loss-of-benefit triggers can help avoid liquidation. Maintaining repayment ability and a strong credit profile are also important. By avoiding contract breaches and practicing prudent fund management, you can delay or prevent forced liquidation.
