止盈和止损是自动触发器，当价格到达你选定的水平时会平掉你的仓位。止盈在你的目标位锁定收益。止损在亏损进一步扩大之前把它限制住。
你可以在下市价单时设置止盈和止损，也可以之后在任何持仓上添加。限价单和 TWAP 单在入场时不支持设置，等仓位开好后再添加。
如何设置
要在已开仓位上添加或更新止盈和止损：在移动端，打开仓位，点击铅笔图标，选择编辑止损/止盈，或者直接点击仓位上的止损和止盈数值。在网页版，点击仓位卡片上止盈/止损旁边的铅笔，或者直接点击止盈或止损价格。
它们按标记价格触发
止盈和止损都由标记价格触发，而不是图表价格。标记价格结合了预言机价格（多家主要交易所的综合价格）和协议上的本地交易活动，所以它可能和你在图表上看到的略有不同。
这意味着你的止盈或止损触发的那一刻，图表上显示的可能是另一个价格。
订单如何成交
触发后，订单会以市价单的形式按当时最优价格成交。
系统内置了 10% 的滑点容忍度，意思是订单会在触发价上下 10% 以内的任何价格成交。
在快速波动的市场中，成交价可能和触发价有明显差距；在极端行情下，价格可能在止损成交前就跳过了你的止损位。
