TARGETS=500 0.1 0.75 0 0 0 0 0The liquidator will attempt to close all perp positions, and balance the tokens in the liqor account after each liquidation. By default it will sell all token assets into USDC. You can choose to maintain a certain amount of each asset through this process by editing the value in the TARGETS environment variable at the position of the asset. You can find the order of the assets in the 'oracles' property of the group in ids.json The program will attempt to make buy/sell orders during balancing to maintain this level.
