I copied and pasted the code for Shiny app, but it doesn't update the FX quotes every 750 ms. I tried it on Firefox and Chrome.

Gmail seems to think that's what I meant to do] Hello all, I'd like to introduce the TFX package which I recently published to CRAN. It is a simple R interface to the free TrueFX Web API. You can use it to get real-time quotes with millisecond resolution and fractional-pip bid/ask spreads for 26 currency pairs. There is an RPub overview of the TFX package available here: http://rpubs.com/gsee/TFX The shiny package (http://www.rstudio.com/shiny/) has made the TFX package more relevant (at least to me). You can see a demo of using TFX with shiny by running the following code which will open a browser window and display FX quotes that update every 750 milliseconds: # install.packages('shiny', repos=c('http://rstudio.org/_packages', # getOption('repos')) library(shiny) runGist("4122626") #-------------------------- The code for the above shiny app can be viewed or downloaded from https://gist.github.com/4122626 I've also had a little bit of success creating real-time streaming charts using svSockets, following the video (http://www.youtube.com/watch?v=rvT8XThGA8o) on the data.table homepage (http://datatable.r-forge.r-project.org/) as a template and using TFX as the data source. Finally, TrueFX provides historical tick data for 15 currency pairs going back to May 2009 (http://truefx.com/?page=downloads). There is a script in the inst/parser directory of the FinancialInstrument package (www.tinyurl.com/DownloadTrueFX) that can be used to download all of that data to disk in a format that FinancialInstrument::getSymbols.FI can easily read. This script is not intended to be used on Windows. I have no affiliation with TrueFX. Hope it's useful, Garrett P.S. The RPub (http://rpubs.com/gsee/TFX) is also included as a vignette in the R-Forge version (installable with install.packages("TFX", repos="http://r-forge.r-project.org";). As outlined in the NEWS file, the only updates in the R-Forge version are aesthetic: there are better error messages, a print.TFXsession method, and Reconnect and Disconnect no longer print the returned TFXsession object. _______________________________________________ [email protected] mailing list https://stat.ethz.ch/mailman/listinfo/r-sig-finance -- Subscriber-posting only.
