The stop-loss price you set is triggered based on the latest price, while liquidation is triggered based on the mark price. When the event occurs, the spot price drops first, causing the significantly strong mark price to drop as well. At that time, the market has not yet declined, and in this situation, when the mark price reaches the liquidation price, it triggers the liquidation, which makes it reasonable for the position to be liquidated. Next time you set a stop-loss, you can consider using the mark price as the trigger price instead of the latest price, and this will solve the problem.
