When a trader’s position is liquidated, the position is taken over by MEXC's perpetual contract liquidation system. If the liquidation cannot be filled by the time the fair price reaches the bankruptcy price, the ADL system will automatically deleverage the positions of traders with reverse positions. The order of deleveraging is based on leverage and profit ratio.   Automatic Deleveraging Ranking System: （1）Deleveraging Process The trader’s positions are liquidated based on the bankruptcy price of the positions. If the insurance fund is still not enough, automatic deleveraging will be triggered. The effective leveraging PNL ranking is calculated by the counterparty based on profits and effective leverage. Traders who trade aggressively and earn the most profits will be marked with ADL sequence priority. Automatic deleveraging at bankruptcy prices of ADL executed parties with the top traders in terms of effective leverage PNL.   Automatic Deleveraging Ranking Calculation: Ranking = PNL Percentage * Effective Leverage  (if profitable)         = PNL Percentage / Effective Leverage  (if loss) where   Effective Leverage = abs(Mark Value) / (Mark Value - Bankruptcy Value)   PNL percentage = (Mark Value - Avg Entry Value) / abs(Avg Entry Value)   Mark Value = Position Value at Mark Price   Bankruptcy Value = Position Value at Bankruptcy Price   Avg Entry Value = Position Value at Average Entry Price   The system will sort these positions from highest to lowest.
