What Is Binance Futures ADL (Auto-Deleveraging)

What Is ADL (Auto-Deleveraging)

ADL (Auto-Deleveraging) is a risk control mechanism in Binance futures trading. When extreme market conditions occur, if the liquidation engine cannot close forcibly liquidated positions at a reasonable price, and the insurance fund is insufficient to cover the losses, the system activates the ADL mechanism.

In simple terms, ADL works as follows: in extreme situations, the system automatically reduces the positions of counterparties (traders with higher profits) to balance out losses. It is a last resort to ensure the overall solvency of the trading system.

ADL Trigger Conditions

ADL is not something that occurs regularly. It is only triggered when all of the following conditions are met simultaneously:

1. A Liquidation Order Is Generated

A trader's position is forcibly liquidated due to insufficient margin.

2. The Liquidation Engine Cannot Execute

The liquidated position cannot be filled at the bankruptcy price (or a better price). This typically happens when market liquidity is extremely poor or prices are fluctuating violently.

3. The Insurance Fund Is Insufficient

Binance maintains an insurance fund to cover liquidation losses. ADL is only activated when the insurance fund balance is insufficient to cover the losses from liquidation.

Under normal market conditions, the insurance fund is usually sufficient to cover liquidation losses, so ADL is rarely triggered. However, during black swan events (such as market flash crashes), the probability of ADL increases.

ADL Indicator Lights

Binance provides an ADL priority indicator for each futures position, helping you understand your risk level of being auto-deleveraged.

Indicator Meaning

The indicator typically uses 1-5 lights to represent your ADL priority:

5 lights lit: Your ADL priority is the highest. If ADL occurs, your position will be reduced first
4 lights lit: High priority
3 lights lit: Medium priority
2 lights lit: Lower priority
1 light lit: Your ADL priority is the lowest; the chance of being deleveraged is minimal

Where to Check

In the Binance App or web platform futures trading interface:

View the ADL indicator in the position details
It's typically displayed as a row of small blocks or lights, with the number lit representing your priority

How ADL Priority Is Determined

The system determines ADL ranking based on the following factors:

Profit Level

Traders with larger position profits have higher ADL priority, as their profits represent the other side of the counterparty's (liquidated party's) position.

Leverage Usage

Positions with higher effective leverage rank higher in ADL. The specific ranking formula is:

ADL Ranking = Profit Ratio × Effective Leverage

That is, a position with high profit and high leverage has the highest ADL priority.

What Happens When ADL Occurs

If your position is auto-deleveraged, the following happens:

Partial or full position is forcibly closed: The system closes part or all of your position at the current mark price
Notification received: You'll receive an ADL notification with the deleveraged quantity and price
Related orders canceled: Pending orders (such as take-profit/stop-loss orders) associated with the deleveraged position are automatically canceled
P&L settled: The deleveraged portion is settled at the current mark price

Although ADL may disrupt your trading plan, note that you don't lose money from it — the closing price is the current mark price, and your previously accumulated profits are preserved.

How to Reduce ADL Risk

1. Lower Effective Leverage

Using lower leverage reduces your ADL priority. Avoid excessively high leverage, as it increases both liquidation risk and ADL risk.

2. Take Profits in Time

Don't be overly greedy. When a position has significant unrealized profits, consider partially or fully closing it. High-leverage positions with large floating profits are the primary targets for ADL.

3. Diversify Positions

Don't concentrate all your funds in one large position. Spreading across multiple smaller positions can lower each individual position's ADL priority.

4. Set Take-Profit Orders

Set reasonable take-profit levels for your profitable positions to automatically close them when targets are reached, avoiding becoming an ADL target during extreme conditions.

5. Monitor Market Developments

Before and after major news events (such as Fed interest rate decisions, significant regulatory announcements), market volatility may intensify. During these periods, consider reducing positions or lowering leverage.

6. Watch the ADL Indicator

Regularly check your positions' ADL indicators. If you notice many lights illuminated (4-5), your ADL priority is high, and you should consider proactively reducing your position.

ADL vs. Liquidation

Many beginners confuse ADL with liquidation:

Liquidation: Your own margin is insufficient, so the system forcibly closes your losing position
ADL (Auto-Deleveraging): Someone else gets liquidated, and the resulting losses can't be covered, so the system reduces your profitable position

Simply put, liquidation happens because you lost money, while ADL happens because you made money but had part of your position "shared."

FAQ

Q: Does ADL happen often? A: Not often. Under normal market conditions, the insurance fund is sufficient to cover liquidation losses, and ADL is rarely triggered. It mainly occurs during extreme market events.

Q: Can I appeal after being ADL'd? A: ADL is an automatically executed risk control mechanism that cannot be appealed or reversed. It's part of the futures trading rules.

Q: Does spot margin trading also have ADL? A: ADL primarily exists in futures trading. Spot margin trading uses different risk control mechanisms.
