Here) for details on your rights to use the actual data downloaded. You should refer to Yahoo!'s terms of use ( here, It's an open-source tool that uses Yahoo's publicly available APIs, and is intended for research and educational purposes. Yfinance is not affiliated, endorsed, or vetted by Yahoo, Inc. Yahoo!, Y!Finance, and Yahoo! finance are registered trademarks of Yahoo, Inc. As a result, my library, yfinance, gained momentum and was downloaded over 100,000 enjoys 300k+ installs per month, acording to PyPi! Here is how you would get the data for AAPL and GOOG.Ever since Yahoo decommissioned their historical data API, Python developers looked for a reliable workaround. To do this, you would need to use lapply in combination with getSymbols. You may also want to get more than one variable. The variable is also saved as an xts object, which is useful as it allows for easy time-manipulation.
If you want to disable this function, you would set auto.assign to FALSE. getSymbols, by default, will save the ticker history as a variable with the ticker name. You might notice that one does not need to save it as a variable. # AAPL.Open AAPL.High AAPL.Low AAPL.Close AAPL.Volume
You can preview the first few rows of the data using the head() function. The data will be loaded in the AAPL variable. # and getOption("") will still be checked for # 'loadSymbols' to automatically load data. # 'getSymbols' currently uses auto.assign=TRUE by default, but will Below is an example that gets the daily history of AAPL from 1 to 1. Once the package is installed, you would use the getSymbols function to download the data. To start using the Quantmod library, you can install and load it in your R environment using the following commands in R console or R Studio (Preferred). This allows for downloading stock data from multiple sources, although Yahoo is the default option. We will use QuantMod R package to download stock data.
