When ADL Triggers
ADL is armed per market by anadl_trigger_threshold parameter. The protocol tracks the Backstop Liquidator’s PnL drawdown from its high-water mark in that market — realized PnL since the mark, plus unrealized PnL — and ADL becomes eligible only once that drawdown is negative and its size reaches the market’s threshold.
When ADL triggers:
- The system identifies the most profitable opposing positions
- These positions are force-closed at the market’s current committed mark price
- Total open interest in the market is reduced
How Positions Are Selected
ADL targets positions based on profitability and leverage. Positions with higher unrealized profit relative to margin used are selected first. This means highly leveraged profitable positions are more likely to be ADL’d than lower-leverage positions with similar profit.Related
