R：如何在Quantmod圖表上添加VWAP？

Question

我正在嘗試使用Quantmod軟件包在圖表上添加VWAP線作為指標。 我沒有收到錯誤，但是什么也沒畫。 請問我做錯了什么嗎？

另外，是否可以將VWAP繪制為圖表上的點，而不是創建指標？

我已經包括了我的代碼和數據集。 謝謝您的幫助。

我的代碼：

#load data
data1<-read.table("EKSO.txt",header=T,sep=",",stringsAsFactors=F)

#calculate total amount traded
data1["TT"]<-data1$Price*data1$Size

#Change the name of Size into Volume
colnames(data1)[4]<-"Volume"

#combine and convert date and time
data1$Date <- strptime(paste(data1$Date, data1$Time), "%m/%d/%Y %H:%M:%S")

#remove Time columns
data1<-data1[-2]

#load xts and zoo library
library(xts)
library(zoo)
library(quantmod)
library(TTR)

#create an xts object
myxts<-xts(data1[,2:4],order.by=as.POSIXct(data1[,1]))


myxts60<-period.apply(myxts, endpoints(myxts, "minutes", 60), function(x) {
  cbind(as.numeric(first(x$Price)),
        as.numeric(max(x$Price)),
        as.numeric(min(x$Price)),
        as.numeric(last(x$Price)),
        sum(x$Volume),
        sum(x$TT))

})
colnames(myxts60)<-c("Open","High","Low","Close","Volume","TT")


#Function to calculate vwap
vwapFct<-function(myxts60){myxts60$TT/myxts60$Volume}

#Draw chart
chartSeries(myxts60,theme=chartTheme('white'),up.col="green",dn.col='red')
#Draw vwap line
addVWAP<-newTA(FUN=vwapFct,on =1, legend="VWAP")

#how to draw VWAP points on Chart

Answer 1

我認為使用addTA可能會更容易。

chartSeries(myxts60,theme=chartTheme('white'),up.col="green",dn.col='red')
addTA(vwapFct(myxts60), on=1)

Answer 2

newTA函數創建一個新函數 。 您需要調用該新函數來實際進行繪圖。

# [ subsetting is more robust and faster than $ subsetting for xts objects
vwapFct <- function(myxts60) { myxts60[,"TT"]/myxts60[,"Volume"] }
# Create addVWAP() function
addVWAP <- newTA(FUN=vwapFct, on=1, legend="VWAP")
# Create theme
myTheme <- chartTheme("white", up.col="green", dn.col="red")
# Draw chart
chartSeries(myxts60, TA="addVo();addVWAP()", theme=myTheme)
# Use normal 'par' values to change the plot
chartSeries(myxts60, TA="addVo();addVWAP(type='p',col='blue')", theme=myTheme)
