In cryptocurrency derivatives trading, understanding a platform's risk management mechanisms is crucial. Bitget Exchange's perpetual contract "protocol liquidation queue" typically refers to its "Auto-Deleveraging" (ADL) mechanism. This is a systemic risk mitigation solution initiated by the platform when extreme market conditions arise and conventional forced liquidation processes cannot fully manage the risk.
Definition and Trigger of the Protocol Liquidation Queue (ADL)
The protocol liquidation queue is not a physical waiting list, but a set of procedures that automatically execute when the insurance fund is depleted or insufficient to cover clawback losses. Its core purpose is that if a user's position is forcibly liquidated (forced liquidation) due to insufficient margin, and the liquidation execution price difference results in a negative account equity (i.e., "clawback"), and the insurance fund can no longer cover this loss, the system will automatically deleverage profitable positions in the opposite direction on the platform, using their profits to cover the system's deficit.
Bitget's Risk Control Mechanism and ADL Process
ADL is the last line of defense in Bitget's multi-layered risk control system. To understand when ADL is triggered, one must first understand its preceding risk control steps:
- Mark Price and Forced Liquidation: Bitget uses a "mark price" calculated from data aggregated from multiple mainstream exchanges to determine the liquidation price and unrealized profit/loss, rather than the real-time transaction price. This helps reduce unnecessary liquidations caused by brief abnormal market fluctuations ("price wicks").
- Tiered Maintenance Margin Rate: Bitget implements a tiered margin system, where larger positions require higher maintenance margin rates and allow lower maximum leverage, thereby controlling systemic risks posed by large positions.
- Insurance Fund: The platform maintains an insurance fund. When a user's forced liquidation results in a small clawback loss, the insurance fund prioritizes covering it. The ADL mechanism is only activated when the insurance fund is insufficient to cover all clawback losses.

When ADL is triggered, the system deleverages profitable opposing positions according to predefined rules. Typically, positions with high profit ratios and high leverage rates are prioritized for deleveraging. Bitget adopts a "gradual deleveraging" approach, meaning only a portion of the profitable position is reduced, rather than full liquidation, to minimize the impact on profitable users.
Other Related Mechanisms for Perpetual Contracts
Perpetual contracts have no expiry date, and their prices are anchored to the spot market through the "funding rate" mechanism. Bitget's funding rate is settled every 8 hours. Traders should note that if a position is forcibly liquidated, the platform charges a certain liquidation fee, which is injected into the risk reserve fund. For specific parameters and real-time market data for futures trading, users can check and verify on market data platforms such as Svmuu.
Significance for Traders
The existence of the ADL mechanism means that in extreme market conditions, even if traders hold profitable positions, they may passively face partial deleveraging. This highlights the two-way risk of high-leverage trading. For Bitget, forced liquidation and ADL are necessary measures to manage overall platform risk and protect system stability. Traders should fully understand the platform's margin requirements, liquidation rules, and risk control mechanisms such such as ADL, use leverage cautiously, and constantly monitor position risk.
