止盈和止損是自動觸發機制，會在價格到達你選定的水位時平掉你的部位。止盈在你的目標價鎖住獲利。止損在虧損進一步擴大之前把它限制住。
你可以在下市價單時設定止盈和止損，也可以之後在任何未平倉部位上加上它們。限價單和 TWAP 委託在進場時不接受這兩項設定；請等部位開啟後再加上。
如何設定
要在已經開啟的部位上添加或更新止盈和止損：在手機上，打開部位，點按鉛筆圖示，選擇「編輯止損/止盈」，或直接點按部位上的止損和止盈數值。在網頁上，點按部位卡片上止盈/止損旁邊的鉛筆，或直接點按止盈或止損價格。
以標記價格觸發
止盈和止損都是由標記價格觸發的，而不是圖表價格。標記價格結合了預言機價格（跨主要交易所的綜合價格）和協議上的本地交易活動，所以它可能和你在圖表上看到的略有不同。
這表示你的止盈或止損可能會在圖表看起來顯示另一個價格的時刻觸發。
委託如何成交
當觸發條件達到時，委託會以市價單的形式按當時最佳可得價格成交。
內建的滑點容許度是 10%，也就是說委託會在你觸發水位 10% 範圍內的任何價格成交。
在快速變動的市場中，成交價格可能和觸發價格有明顯差距；在極端行情下，價格可能在止損成交之前就跳空越過它。
