感谢您的答案，那个地方是我自己改错了！:$ 现在按您的意见修改后，出现新的编译问题！请再帮我看看好吗？谢谢啦！ 'SpeechText' - function is not defined C:\PROGRAM FILES\METATRADER 4\experts\indicators\Alert.mq4 (84, 10) 'SpeechText' - function is not defined C:\PROGRAM FILES\METATRADER 4\experts\indicators\Alert.mq4 (91, 10)

复制过去就可以了。 你需要的是只是声音报警功能，所以SpeechText去掉即可。
