# Auto-Deleveraging (ADL)

ADL (Auto-Deleveraging) is the final step in the liquidation process, a last-resort safety feature used when a bankrupt position can't be liquidated normally due to market conditions: Aevo will close the most profitable, highest-leveraged positions first to maintain system stability.

In the ADL system, traders are placed in an ADL priority queue. The higher your rank is in the queue, the higher the likelihood that your position will be auto-deleveraged. The calculation for the rank is stated below.

On the UI, your ADL rank is shown for each position. The more bars that are lit, the higher the likelihood that your position will be ADL-ed.

When auto-deleveraged, both accounts will trade at the mark price.

***Options and perps on majors (BTC, ETH, SOL) are currently not under ADL.***

## ADL Rank Calculation

The higher the rank, the higher the likelihood of ADL.

```
PNL Percent = UPNL / Max(1, Balance)

If PNL Percentage ≤ 0, then Margin Ratio = 0
If PNL Percentage > 0, then Margin Ratio = Maintenance Margin / (Balance + UPNL)

ADL Score = PNL Percent * Margin Ratio
```
