Auto-Deleveraging (ADL) is the final step taken only when the Insurance Fund cannot accept the bankrupt client’s positions. Binance takes every possible step to avoid auto-deleveraging, and has several features such as Immediate or Cancel Limit Orders to minimize the potential impact of any auto-deleveraging when it does occur. Unfortunately, due to the volatility in the crypto markets, and the high leverage offered to users, it is not possible to fully avoid auto-deleverage liquidations. In order to provide the best possible user experience, we are striving to keep auto-deleveraging liquidations to an absolute minimum.
As a trader, your position is at risk of auto-deleveraging based on an indicator with your priority in the queue. Below is an example of the indicators, from lowest priority to highest priority.
When there is an auto-deleverage liquidation, a notice is immediately sent to the affected user.
The trader’s position in the priority ranking is calculated by both profit and leverage; the formula is presented at the end of this page. More profitable and higher leveraged traders will be liquidated first. The exact formulation is at the end.
From there, traders will be ranked by the LeveragePnlQuantile term; traders at imminent risk of being automatically liquidated will see the appropriate indicator in their interface. If the liquidation occurs, the trader will be sent a notice with the amount and liquidation price. The trader’s positions will be closed out at the bankruptcy price of the initial liquidated order, no trading fee will be charged. Any open orders will be canceled. Once the liquidation process is completed, the trader will be able to re-enter immediately.
Note: Bankruptcy price may be out of the contract’s market price range. It is highly recommended that the trader pays attention to the ADL indicator to avoid being deleveraged.
Calculation for Liquidation Priority Ranking
PNL Percentage = Unrealized Profit/abs(Position Notional)
Effective Leverage = abs(Position Notional) / (Wallet Balance + Unrealized Profit)
If PNL Percentage ≥ 0, then ranking = PNL Percentage * Effective Leverage
If PNL Percentage < 0, then ranking = PNL Percentage / Effective Leverage
Leverage PNL Quantile = rank(user.ranking)/Total User Count
* For Portfolio Margin, Effective Leverage = abs(Position Notional)/ accountEquity
