What is Forced Liquidation?
Forced liquidation (or "margin call") occurs when a trader's account maintenance margin ratio falls to 100% or below. This means the account's total equity equals or falls below the required maintenance margin plus liquidation fees. At this point, the system automatically triggers risk control measures to protect both the platform and users from excessive losses.
Key Mechanisms:
- Automatic cancellation of pending orders
- Partial or full position liquidation
- Risk-tiered approaches based on position size
- Varies by account type and product
Pro Tip: Regularly monitor your positions and maintain sufficient margin to avoid forced liquidation scenarios.
Maintenance Margin Requirements Explained
The maintenance margin ratio represents the minimum percentage of equity required to keep positions open. This dynamic percentage changes based on:
A. Account Types
Isolated Margin Mode
- Each position calculates risk independently
- Margin requirements don't affect other positions
Cross Margin Mode
- All positions share combined equity
- Higher risk but more flexibility
Multi-Currency & Portfolio Margin
- Advanced risk modeling determines requirements
- Stress-tested against potential losses
B. Position Tiers (Risk Layering)
- Larger positions move to higher risk tiers
- Each tier has increased margin requirements
- Designed to manage systemic risk and leverage
- Platforms regularly update tier standards

Fees Associated with Liquidation
When maintenance margin hits 100% or below, these fees apply:
Liquidation Fees Structure
Standard Liquidation Fee
- Based on user's fee tier
- Options carry additional 12.5% premium fee
Liquidation Slippage Fee
- Covers market impact costs
- Net gains fund the platform's risk reserve
Calculation Examples:
| Account Type | Calculation Method |
|---|---|
| Spot & Margin | ABS(Debt) × Currency Pair Maintenance Rate |
| Futures | Contract Size × Mark Price × Tier Rate |
| Options | Premium × Multiplier × Liquidated Lots |
The Liquidation Process Step-by-Step
When triggered, the system follows this sequence:
Order Cancellation Phase
- All pending orders are automatically canceled
- New orders requiring additional margin are blocked
Position Reduction Phase
- System takes control of risky positions
- Highest-risk positions liquidated first
- Priority given to debt repayment
Multi-Currency Handling
- Non-USDT debts: Position reduction starts from liability side
- USDT debts: Asset-side liquidation using discount rate tiers

FAQ Section
Q: How can I check my maintenance margin ratio?
A: Most platforms display this prominently in your account dashboard. You can typically find it alongside your position details and equity information.
Q: What's the difference between isolated and cross margin liquidation?
A: Isolated margin only liquidates the specific position that triggered the margin call, while cross margin may liquidate any position in your account to cover the deficit.
Q: Can I recover funds after liquidation?
A: Once liquidation occurs, positions are closed at market prices. Any remaining equity (after covering losses and fees) stays in your account.
Q: How often do maintenance margin requirements change?
A: Requirements can change daily or even intraday based on market volatility and your position size. Always check current requirements before placing trades.
Q: Are there ways to avoid liquidation completely?
A: While you can't eliminate the possibility, using conservative leverage, maintaining margin buffers, and actively monitoring positions significantly reduce liquidation risks.
Q: Do all trading products have the same liquidation rules?
A: No, futures, options, and spot markets each have unique liquidation parameters. Always review product-specific documentation before trading.
Remember: Trading involves substantial risk of loss. Only trade with funds you can afford to lose, and consider consulting with a financial professional before engaging in margin trading. Platforms reserve the right to modify liquidation policies, so stay updated on current terms.
