Today I ate a big pit myself and learned more about adl and how to avoid it. Simply put, it means that your counterparty in the contract has liquidated their position and needs to be liquidated, but the market liquidity is insufficient. So your order may be subject to ADL. The order of Adl is based on the opening time, return rate (after leverage), and overall risk rate of your account For example, if the price drops to $2.7 and you short FIL at $4 or $5x, you will also be ahead of others who short at $3 or $10x So how to avoid ADL is to lower the leverage ratio during the decline process. (If you short 10x and drop 10%, you can double your principal and adjust it to 5x) By the way, we used to use risk margin before, which means that if you sell out, you will charge a certain handling fee to inject the risk margin to compensate for the loss caused by the liquidation. Later, Binance invented ADL, and now there is almost no liquidation, but the risk margin remains unchanged, which means that all the slippage losses from your liquidation are taken by the exchange.
