According to Ai 姨 (@ai_9684xtpa), a significant ETH long position of 160,234.18 ETH ($306 million) was liquidated at $1,915 by the HLP (Hyperliquidity Provider) system. Due to the enormous size of the position, the liquidation process caused ETH to drop further, resulting in losses that were absorbed by the HLP system. This event highlights the risks associated with large leveraged positions in volatile markets.
