意思是止损，例如：
1、Never cancel a stop loss order after you have placed it!设定了止损价位，不会因任何原因而取消。
2、If the market moves to your stop loss price， you should get out every single time.一旦市场移动到你的止损位，你要第一时间止损。
3、Set objectives for the investment club at each meeting and always set a stop loss for every investment.在每次会议都为俱乐部设立一个目标，始终为每一笔投资设置一个止损点。
