Deconstructing the Risks of Perpetual Futures and the Risk Control Mechanisms of Exchanges

Perptual Futures, as a complex financial derivative, are characterized by high leverage and high risk. To maintain market stability and fairness, the exchange has established a rigorous risk management system. This article will delve into the core components of this system, including the margin mechanism, forced liquidation process, risk protection fund, and automatic position reduction mechanism, to help traders better understand and cope with the risks in contract trading.

Core Risk Management Framework for Perpetual Futures

The risk management system of Perptual Futures is a multi-layered defense structure, mainly including the following three pillars:

1. Forced liquidation: When a trader's margin is insufficient to maintain a position, the system will automatically close the position to control risk.

2. Risk Protection Fund: Used to compensate for losses due to margin calls caused by severe market fluctuations.

3. Automatic Deleveraging Mechanism ( ADL ): In extreme cases, the entire system is protected by forcibly closing profitable positions.

These three mechanisms form a risk control chain from individual to system, aiming to isolate the risk of a single account and prevent it from spreading to the entire trading ecosystem.

Margin and Leverage: The Basis of Risk

Margin is the collateral that traders must deposit to open and maintain leveraged positions. It is divided into two key levels:

• Initial Margin: The minimum amount of collateral required to open a position.
• Maintenance Margin: The minimum collateral amount required to maintain an open position.

Exchanges usually offer various margin models, including isolated, cross, and combined margin, to meet the needs of different traders.

In order to prevent a single trader from holding an excessively large position, exchanges generally implement a tiered margin system. As the position size increases, the system will automatically reduce the maximum available leverage and increase the maintenance margin rate, effectively controlling risk.

Liquidation Trigger: Key Price Indicator

The exchange uses a specialized price indicator system to execute forced liquidation, mainly including:

• Mark Price: The calculated price that reflects the "fair value" of the contract, which is the basis for triggering liquidation.
• Liquidation Price: When the mark price reaches this price, forced liquidation is triggered.
• Liquidation Price: The price point at which the trader's initial margin is completely lost.

The range between the liquidation price and the bankruptcy price constitutes the "operational buffer zone" of the exchange's risk engine.

Forced Liquidation Process

When the mark price reaches the liquidation price, the exchange will initiate the following process:

1. Cancel unfilled orders
2. Partial Position Closing or Tiered Liquidation
3. Fully Close Position

In addition to bearing position losses, traders are also required to pay an additional liquidation fee. This fee will be injected into the risk guarantee fund to address potential future liquidation losses.

Risk Guarantee Fund and Automatic Liquidation Mechanism ( ADL )

The risk assurance fund is a capital pool established by the exchange to compensate for the losses incurred due to forced liquidation. Its funds mainly come from forced liquidation fees and profits from forced liquidations.

When the risk protection fund is exhausted, the exchange will activate the automatic liquidation mechanism ( ADL ). ADL will choose the most profitable and highly leveraged short positions in the market for forced liquidation to compensate for the system losses.

Conclusion

The risk management system of Perptual Futures is a carefully designed multi-layered defense structure. Although the exchange provides powerful automated risk management tools, traders still need to use leverage cautiously, set reasonable stop-losses, and closely monitor their own position risks. Only by fully understanding and following these rules can one survive in the high-risk Perptual Futures market in the long term.
