Details

Meant to be called internally by getSymbols only. This method is not meant to be called directly, instead a call to getSymbols("x", src="tiingo") will in turn call this method. It is documented for the sole purpose of highlighting the arguments accepted.

You must register with Tiingo in order to download their data. Register at their web site, https://www.tiingo.com, and you will receive an API key: a short string of alphanumeric characters (e.g., "FU4U"). Provide the API key every time you call getSymbols; or set it globally using setDefaults(getSymbols.tiingo, api.key="yourKey").

Tiingo provides daily, weekly, monthly, and annual data. Use periodicity to select one. This API accessor will return adjusted or unadjusted OHLC as well as split and dividend information.

For daily, weekly, and monthly data, Tiingo says the available data is up to 30 years;

Examples

Run this code

if (FALSE) {
# You'll need the API key given when you registered
getSymbols("IBM", src="tiingo", api.key="yourKey")

# Repeating your API key every time is tedious.
# Fortunately, you can set a global default.
setDefaults(getSymbols.tiingo, api.key="yourKey")
getSymbols("IBM", src="tiingo")
}
