Update: A user suggested making use of the quantmod::adjustOHLC() function as the adjusted close of Yahoo data is currently incomplete, and doesn’t account for dividends. I don’t know when that will happen, but I have been using the branch version for a few days now, and all appears to be working as expected. Of course, if you don’t want to update quantmod to a version that lives on a Git branch, you can wait until the changes are merged into master and doĭevtools::install_github(“joshuaulrich/quantmod”) Once the package updates, quantmod::getSymbols(src = “yahoo”) should work just as it did prior to the updates on the Yahoo Finance server. Of course, you need the devtools package installed, so do install.packages(“devtools”) first if you don’t already have it installed. 
You can update your quantmod package to the development version that addresses this issue using this command in R:ĭevtools::install_github(“joshuaulrich/quantmod”, ref=”157_yahoo_502″) Users of the excellent R package quantmod however are in luck! The package’s author, Joshua Ulrich, has already addressed the change in a development version of quantmod. No doubt this is a huge source of frustration, as many backtesting and trading scripts that relied on such data will no longer work. Specifically, Yahoo Finance switched from HTTP to HTTPS and changed the data download URLs. Recently, Yahoo Finance – a popular source of free end-of-day price data – made some changes to their server which wreaked a little havoc on anyone relying on it for their algos or simulations.
