In the fast-paced world of cryptocurrency derivatives trading, risk management is critical — both for traders and for the platforms facilitating these high-leverage transactions. One of the most sophisticated safety mechanisms employed by leading exchanges is the Auto-Deleveraging (ADL) system, designed to protect market integrity during periods of extreme volatility. This article dives deep into how OKX’s Auto-Deleveraging mechanism works, the role of risk provision funds, and what it means for your trading strategy.

What Is Risk Provision Fund?
The risk provision fund is a safeguard mechanism used by OKX to absorb potential losses from liquidated positions when market prices move too rapidly for orderly execution. If a trader's position is liquidated and the system cannot close it at a sufficient price — resulting in a "clawback" or deficit — this fund helps cover the shortfall, preventing losses from spilling over to other users.
This fund is primarily sourced from two channels:
- Initial capital contributions provided by the OKX platform.
- Residual value recovered after forced liquidations.
Importantly, each product line on OKX maintains its own independent risk provision fund:
- Margin Trading
- Futures (Delivery Contracts)
- Perpetual Swaps
- Options
Furthermore, within each product line, funds are segmented by underlying asset and settlement currency, ensuring isolation of risks across different markets.
Risk Fund Structure by Product Line
Margin Trading
In margin trading, risk provision funds are separated by base and quote currencies. Each leveraged trading pair contributes to the risk pools of both involved currencies.
For example:
- BTC/USDT → contributes to BTC and USDT risk pools
- ETH/BTC → contributes to ETH and BTC pools
- ETH/USDT → contributes to ETH and USDT pools
Thus:
- The BTC risk pool accumulates funds from all positions involving BTC as either base or quote.
- The USDT pool aggregates residual value from all USDT-denominated pairs.
Delivery Contracts
For futures (delivery) contracts:
- Coin-margined contracts (e.g., BTCUSD) maintain risk funds in their respective coin (BTC).
- USDT-margined contracts (e.g., ETHUSDT) use USDT as the settlement currency for their risk fund.
While all USDT-margined delivery contracts use USDT, each underlying asset has its own isolated pool. That means ETHUSDT and XRPUSDT contracts do not share the same USDT risk fund — they remain separate.
Additionally, all expiration dates (weekly, bi-weekly, quarterly) for the same underlying asset share one unified risk fund.
Perpetual Contracts
Similar to delivery contracts:
- Coin-margined perpetuals (e.g., BTCUSD) have risk funds in their native coin.
- USDT-margined perpetuals (e.g., ETHUSDT) use USDT, but again, each underlying has its own isolated USDT pool.
This ensures that a sharp move in one market doesn’t deplete resources needed to stabilize another.
Options
Options contracts also maintain isolated risk provision funds by underlying asset. All options on the same underlying — regardless of strike price, expiration date, or call/put type — contribute to a single risk fund denominated in that asset (e.g., BTC for BTCUSD options).
Every day at 16:00 HKT, OKX reconciles the previous 24 hours of gains or losses from forced liquidations and adjusts the risk provision fund accordingly. Any surplus is withdrawn; any deficit is replenished from platform reserves.
How Auto-Deleveraging (ADL) Works
Despite robust risk funds, extreme market conditions — such as flash crashes or black swan events — can overwhelm available reserves. When this happens, OKX activates its Auto-Deleveraging (ADL) mechanism.

ADL kicks in under two scenarios:
- The risk provision fund is insufficient to cover a liquidation deficit.
- The fund drops 30% below its peak within 8 hours, indicating rapid market stress. (Note: This threshold may be adjusted based on market conditions.)
Once ADL is triggered, instead of waiting for market orders to fill the gap, OKX directly matches losing positions with profitable opposing positions, using the mark price for execution.
This means:
- The losing position is closed.
- The profitable counterparty’s position is partially or fully reduced.
- The counterparty’s unrealized profit becomes realized balance.
After ADL execution, no further loss distribution (like socialized loss sharing) occurs — making ADL a final line of defense.
ADL Counterparty Ranking System
Not all profitable traders are equally likely to be selected during ADL. OKX uses a smart ranking algorithm based on two key factors:
- Position profitability
- Risk exposure (measured via margin ratio)
The system calculates a "leverage gain" score depending on the account mode:
| Position Mode | Profitable Position Formula | Losing Position Formula |
|---|---|---|
| Isolated Margin | Return / Margin Ratio | Return × Margin Ratio |
| Cross-Margin (Single Asset) | Return / Account Margin Ratio | Return × Account Margin Ratio |
| Multi-Currency Cross & Portfolio Margin | Return / Account Margin Ratio | Return × Account Margin Ratio |
Higher leverage gain = higher chance of being selected as an ADL counterparty.
What Does This Mean for You?
Positions with:
✅ High returns
✅ Low margin ratios
→ Are more likely to be hit by ADL
Conversely:
❌ Low returns
❌ High margin ratios
→ Lower ADL risk
To help users monitor exposure, OKX provides a real-time ADL indicator — a 5-bar signal light visible on the trading interface:
- 🔴 5 bars lit = High risk (you’re near the top of the match list)
- 🟢 1 bar lit = Low risk (you’re safely ranked lower)
After an ADL event, affected users receive email and SMS notifications detailing:
- Which position was reduced
- Execution price (based on mark price)
- Timestamp
You can also review the transaction in your Order History, labeled as “Auto-Deleveraging.”
Frequently Asked Questions (FAQ)
Q: Does ADL mean I’ll lose money even if I’m profitable?
A: Yes — if your profitable position is selected as a counterparty, it will be reduced to cover losses from failed liquidations. However, your unrealized gain becomes realized, so you still retain profits up to the point of closure.
Q: Can I avoid being hit by ADL?
A: Yes. Lower your leverage, increase your margin buffer, or close highly profitable positions proactively. Monitoring the ADL indicator helps you stay aware of your risk level.
Q: Is ADL the same as socialized loss sharing?
A: No. Socialized loss sharing spreads losses across all users — which OKX avoids thanks to ADL. ADL targets only those with high-risk/high-reward profiles, preserving fairness.
Q: Are spot or margin accounts affected by perpetual contract ADL?
A: No. Risk funds and ADL systems are strictly siloed by product type and asset. Only positions within the same contract category are involved.
Q: How often does ADL occur?
A: Rarely — only during extreme volatility when risk funds are strained. Historical data shows it activates infrequently but plays a crucial role when needed.
Q: Is the mark price fair for ADL execution?
A: Yes. The mark price reflects fair market value using a basket of spot prices and funding rates, preventing manipulation during volatile swings.
