In 2 steps: Technical Analysis in R-Project

Getting the right charts when you require them can always be tricky which translates to searching for hours on the internet or sometimes even paying for them. But what do you do when you have to get the updated online data all the time? Below is the R-Project code which will help in visualizing the online financial data. In this tutorial, we use “quandmod” package and yahoo data through systematicportfolio.com to Chart the financial data.

Install R-Project from the link below

• Windows
• Mac

Once Installed Please Copy-Paste the code below in the R-Console Window

# Step 1: Creating a function called anomalies_plot. 
# So that we dont have to write the code again 
# Once the function is created we can use it in future analysis/charting as well.


# Getting the required Library
list.of.packages <- c("quantmod")
new.packages <- list.of.packages[!(list.of.packages %in% installed.packages()[,"Package"])]
if(length(new.packages)) install.packages(new.packages)
library('quantmod')
# Creating Funtion
anomalies_plot <- function(symbol, start_date, end_date) {
# Download data from Yahoo Finance
data <- getSymbols(symbol, src = "yahoo", from = start_date, to = end_date, auto.assign = FALSE)
# Plot the data
chartSeries(data, name = symbol, theme = "white", major.ticks = "auto")
}

#Step 2: Calling the function anomalies_plot for Symbol "AAPL" from 2015, January 01 till today
anomalies_plot("AAPL","2015-01-01",Sys.Date())

The current indicators from the TTR package, as well as a few originating in the “quantmod”, package are:
