Liquidation, often referred to as "爆仓" in Chinese financial contexts, occurs when an investor's margin account equity turns negative due to adverse market conditions. This high-risk scenario arises primarily from leveraged trading, where market volatility amplifies losses beyond the initial investment.
How Liquidation Happens
Margin Account Dynamics
- When market trends shift dramatically against a trader's position, the majority of funds in their margin account become locked as collateral.
- Leverage magnifies both gains and losses. A 10:1 leverage means a 10% price drop wipes out the entire margin.
Critical Triggers
- Position Overload: Excessive leverage with heavy positions reduces risk tolerance.
- Market Gaps: Sudden price jumps (e.g., overnight gaps) can bypass stop-loss orders.

Primary Causes of Liquidation
| Cause | Description | Prevention |
|---|---|---|
| Overleveraging | Using high leverage with large positions | Limit leverage to 5:1 or lower |
| No Stop-Loss | Failure to set automatic exit points | Always set stop-loss at 2-3% of capital |
| Emotional Trading | Holding losing positions hoping for reversal | Follow strict trading plans |
| Market Gaps | Unpredictable price jumps during closed markets | Avoid holding positions overnight |
Case Study: A Liquidation Scenario
An investor starts with $200,000 margin:
Day 1: Buys 15 contracts at 1200 points (CSI 300 Index Futures). Market drops to 1195 at close.
- Loss: $7,500 | Remaining equity: $192,350
Day 2: Market crashes to 1150 points.
- Additional loss: $67,500 | Equity now $124,850
Day 3: Forced liquidation at 1055 points after failure to meet margin call.
- Final debt: -$17,800
This demonstrates how unchecked losses cascade into debt obligations.
Prevention Strategies
- Position Sizing
Never risk >2% of capital on a single trade. For a $100k account, maximum loss per trade should be $2,000. - Leverage Control
Conservative traders use ≤3:1 leverage. High leverage (10:1+) increases liquidation risks exponentially. Continuous Monitoring
- Track markets in real-time, especially for futures/derivatives
- Set price alerts for critical levels
