Usage

You can see the details of how each function works in vignette

The following demonstrates the usage of the function doji() using Microsoft (ticker: MSFT). We use quantmod package to download data:

library(quantmod)
getSymbols("MSFT", from = "2011-07-08" , to = "2011-07-19")

We first plot the candle chart first:

candleChart(MSFT,theme='white')

We can see that July 11, 12, 13, and 18 are likely to follow doji pattern. Let us see if we can capture using the function doji:

doji(MSFT)

##             doji
## 2011-07-08 FALSE
## 2011-07-11  TRUE
## 2011-07-12  TRUE
## 2011-07-13  TRUE
## 2011-07-14 FALSE
## 2011-07-15 FALSE
## 2011-07-18  TRUE
## 2011-07-19 FALSE
