请看这个：https://www.mql5.com/en/forum/general

将快速平均线的周期设置为1，那么它将与价格越过移动平均线（slo ma）的情况相同。

非常好!谢谢你mladen

如何在Smartfone上添加警报？

代码是:....

.... 但警报显示的是每一个现在的蜡烛！！！我有数字 "推 "MetaQuotes ID。

我有数字 "push "MetaQuotes ID。

测试正常。

有什么问题吗？

什么是错的？

你没有任何标准来决定何时发送通知（类似于 "if (condition==true) SentNotification("alert");）。添加 "如果 "条件，何时执行？

它应该在启动程序中，而不是在脱机程序中（因为脱机程序只有在指标因任何原因停止时才会执行）

警报是只改变颜色的蜡烛。

你为什么不简单地使用任何一个已经正确编码的非滞后的mas呢？你的t变量值从来没有被分配一个合适的值--其余的dU没有检查，因为仅此一点就可以阻止所有的正确计算。
