How Does Binance Auto Deleveraging (ADL) Work?

Core Mechanism of ADL

1. ADL activates only when the insurance fund is insufficient to cover losses from forced liquidations.

2. The system identifies positions with positive unrealized PnL and leverages ≥25x as primary candidates.

3. It calculates a risk score using PnL% multiplied by effective leverage, where PnL% = unrealized profit / absolute position notional value.

4. Positions are ranked in descending order of this score; higher scores indicate higher priority for reduction.

5. Once triggered, ADL executes partial or full closure of selected positions without user consent or notification delay.

Trigger Conditions

1. Market-wide long-short imbalance exceeds 0.3% for over 15 seconds.

2. Uncovered shortfall from liquidations surpasses 120% of the current insurance fund balance.

3. Order book depth fails to absorb liquidation orders at fair price levels within defined slippage thresholds.

4. Simultaneous cascade liquidations across multiple assets exceed platform-wide risk tolerance parameters.

5. No manual override exists—activation is fully algorithmic and irreversible once initiated.

Position Selection Criteria

1. Only positions with realized or unrealized profit are eligible for ADL intervention.

2. Mixed positions containing both closed and open segments are excluded from consideration.

3. Leverage weighting applies: a 100x position carries 3.2× the risk weight of a 10x position.

4. Notional value contributes 25% to the final ranking score, independent of trading fees or funding costs.

5. Accounts holding multiple contracts across different underlying assets undergo separate ADL evaluation per asset class.

Risk Fund Transparency

1. Binance publishes real-time insurance fund balances on its official website dashboard.

2. Historical ADL events are logged with timestamps, affected contract types, and aggregate notional value reduced.

3. Color-coded risk indicators appear beside active positions to reflect proximity to ADL thresholds.

4. Users can monitor their individual ADL ranking percentile via the “Risk Metrics” tab under margin settings.

5. Fund replenishment occurs automatically through a portion of trading fees allocated to the insurance pool.

Impact on Market Equilibrium

1. ADL enforces strict nominal value parity between long and short sides across all perpetual markets.

2. It prevents systemic insolvency by redistributing loss exposure among profitable counterparties.

3. No new capital injection is required—the mechanism relies solely on reallocating existing equity.

4. Settlement occurs instantly upon trigger, bypassing order book matching logic entirely.

5. The process maintains solvency but may cause temporary divergence between index price and mark price during execution.

Frequently Asked Questions

Q1. Does ADL affect spot trading accounts?ADL applies exclusively to perpetual and futures contracts; spot balances remain untouched regardless of market conditions.

Q2. Can users opt out of ADL participation?No opt-out option exists—ADL eligibility is inherent to holding leveraged derivative positions on the platform.

Q3. Are ADL-triggered closures subject to standard fee structures?Yes, all applicable taker fees, funding rate accruals, and settlement charges apply as if executed manually.

Q4. How does ADL interact with cross-margin and isolated-margin modes?ADL operates independently of margin mode selection; both cross-margin and isolated-margin positions undergo identical scoring and selection protocols.
