Real time stock price R [closed]

My qmao package has getQuote "methods" for both BATS and google which are both near real time

Sys.time()#[1] "2014-11-19 14:27:48.727988 CST"getQuote("SPY", src="google")#              TradeTime   Last Change PctChg Exchange GoogleID#SPY 2014-11-19 15:27:00 205.17  -0.38  -0.18 NYSEARCA   700145getQuote("SPY", src="bats", what="bbo")#  TradeTime BidSize BidPrice AskPrice AskSize   Last LastSize row.names#1  15:27:24   15000   205.16   205.17     300 205.17      300       SPY

getQuote.bats has a few options for how you want the data to print:

getQuote("SPY", src="bats", what="ladder")#  SPDR S&P 500 ETF TR TR UNIT #  Time:    15:27:44 #  Volume:  8779553 #  Last: 300 @ 205.17##+-------+--------+-------+#|       | 205.21 | 16700 |#+-------+--------+-------+#|       | 205.2  | 21900 |#+-------+--------+-------+#|       | 205.19 | 17300 |#+-------+--------+-------+#|       | 205.18 | 5572  |#+-------+--------+-------+#|       | 205.17 |  300  |#+-------+--------+-------+#| 15000 | 205.16 |       |#+-------+--------+-------+#| 12100 | 205.15 |       |#+-------+--------+-------+#| 11300 | 205.14 |       |#+-------+--------+-------+#| 23900 | 205.13 |       |#+-------+--------+-------+#| 10600 | 205.12 |       |#+-------+--------+-------+getQuote("SPY", src="bats", what="depth")### BidQty   BidPrice   AskPrice   AskQty #-------- ---------- ---------- --------# 15000     205.16     205.17     300   # 12100     205.15     205.18     5572  # 11300     205.14     205.19    17300  # 23900     205.13     205.2     21900  # 10600     205.12     205.21    16700  

There are also plot methods

plot(getQuote("SPY", src="bats"))

plot(getQuote("SPY", src="bats", what="ladder"))

plot(getQuote("SPY", src="bats", what="depth"))

And, if you're still reading, there is a shiny app included in the package so you can make those "plots" update in real time. Just run this:

shinyBATS()

IB would probably be best for real-time stock data. You won't need to pay for it (*), but last time I looked you will need to open an account with a minimum amount of real money.

There is an R package: http://cran.r-project.org/web/packages/IBrokers/index.html

There is a vignette on getting real-time data, but it was last updated in 2009, so I would go with the general vignette: http://cran.r-project.org/web/packages/IBrokers/vignettes/IBrokers.pdf which was last update sep 2014.

(*: Not strictly true: for some exchanges you will need to pay an extra exchange fee.)
