漆学军：均线交叉，金叉做多，死叉做空的例子程序

《MT4EA编程速成教程》中第33页习题

第一题：将交易信号改成均线交叉，金叉做多，死叉做空。

金叉死叉，需要获取小均线两个点，大均线两个点，然后比较四个点的大小变化，就能判断金叉和死叉。

当黄色为小均线，红色为大均线当 A>B 并且 C>D 就是金叉。

当黄色为大均线，红色为小均线当 A>B 并且 C>D 就是死叉。

在之前一单一结的EA基础上，只需要修改signal（）这个信号函数。

代码修改如下：

int signal(){int res=0;double smallma1=iMA(NULL,0,8,0,MODE_SMA,PRICE_CLOSE,1);double bigma1=iMA(NULL,0,26,0,MODE_SMA,PRICE_CLOSE,1);double smallma2=iMA(NULL,0,8,0,MODE_SMA,PRICE_CLOSE,2);double bigma2=iMA(NULL,0,26,0,MODE_SMA,PRICE_CLOSE,2);if(smallma1>bigma1 && smallma2<bigma2){res=1;}if(smallma1<bigma1 && smallma2>bigma2){res=-1;}return(res);}

完整代码如下：
