在合约交易中，当亏损把保证金几乎耗尽时，交易所自动把你的仓位全部平掉，这个过程叫爆仓（强平/清算）。In derivatives trading, liquidation is when the exchange automatically closes your entire position because your losses have eaten through nearly all of your margin.
爆仓价格和当前价格之间的距离，直接反映一个仓位还有多少"缓冲空间"；市场上大量集中的爆仓单被触发时，往往会在短时间内推动价格出现一段急促的单向移动。The gap between a position's liquidation price and the current market price shows how much buffer that position has left; when a large cluster of liquidation orders gets triggered at once, it can push prices sharply in one direction within a very short window.
