我真的很困难重复移动平均交叉计算。这里是我的尝试：更简单的方法来计算多个移动平均交叉
ma.crossover = function(x){
for(i in seq(1, length(MergedData))) {
ma20 <- SMA(Cl(MergedData[[i]]), n=20)
ma50 <- SMA(Cl(MergedData[[i]]), n=50)
merge_20_50 = na.omit(merge(ma20[50:length(ma20)], ma50))
sma.sig <- ifelse(merge20_50[,1]>merge20_50[,2], 1, ifelse(merge20_50[,1]==merge20_50[,2], 0, -1))
}
}
但后来我最终得到：
>ma <- ma.crossover(MergedData)
NULL
我的数据是这样的：
[[1]]
Date Eur.high Eur.low Eur.close
2016-08-30 1.1192 1.1153 1.1161

而且这样下去，直到[[29]]。我dput的样子：

我要计算的交叉移动所有货币的平均值，但我想尝试使用这个功能用for（）循环，所以我没有写出来的同样的事情在R. 29倍不幸的是，我真的只有R.
这是我想要的一种货币做的示例代码非常基本的知识：
Eur = MergedData[[1]]
dataxts<-xts(Eur[2:4], order.by=Eur$Date)
ma20 <- SMA(Cl(dataxts), n=20)
ma50 <- SMA(Cl(dataxts), n=50)
merge20_50 <- na.omit(merge(ma20[50:length(ma20)], ma50))
##Signals (1 cross up, 0 no cross, -1 cross down)
sig <- ifelse(merge20_50[,1]>merge20_50[,2], 1, ifelse(merge10_20[,1]==merge10_20[,2], 0, -1))
而这个回报：
SMA
2016-02-19 1
2016-02-20 -1
2016-02-21 0
2016-02-22 1
2016-02-23 1
AI在想，如果有对所有29种不同的货币代码这个不那么单调乏味的方式，如果有一种方法，所有的信号合并成一个台，使得我有类似：
Eur.SMA GBP.SMA
2016-02-19 1 0
2016-02-20 -1 0
2016-02-21 0 1
帮助将非常感谢！
