弃单英语怎么说

弃单英文可以译为"abandoned order"或"orphan order"。这个词来源于股市投资领域，指的是交易员在交易平台上下达的买卖指令，但因为某些原因（通常是因为股票价格发生了比预期更大的波动）而未能在交易时间内完成交易。

例句：

The trader abandoned the order when he realized that the stock price had risen too quickly.
(当交易员意识到股票价格上涨得太快时，他弃单了。)
The broker received several orphan orders from clients who had lost internet connectivity.
(经纪人收到了几个客户的弃单，因为这些客户失去了互联网连接。)
