Creates one or more ticker objects for accessing data for ticker symbols. This function handles both single and multiple ticker symbols and validates the provided ticker symbols.
Value
For a single symbol: A list containing ticker data and methods with class "yf_ticker" For multiple symbols: A list containing multiple ticker objects with class "yf_tickers"
Rate Limiting
Yahoo Finance does not provide official API documentation or rate limits. Based on community observations, there are approximate limits of a few hundred requests per day from a single IP address before throttling may occur. When working with multiple tickers, consider:
Batching requests when possible
Adding delays between requests using
Sys.sleep()Caching results for frequently accessed tickers
Using the batch functions (e.g.,
get_tickers_history()) instead of individual calls
Examples
if (FALSE) { # \dontrun{
# Get a single ticker
apple <- get_tickers("AAPL")
# Get historical data for a single ticker
apple_history <- get_history(apple)
# Get company information for a single ticker
apple_info <- get_info(apple)
# Get multiple tickers
tech_tickers <- get_tickers("AAPL", "MSFT", "GOOG")
# Get information for multiple tickers
tech_info <- get_tickers_info(tech_tickers)
# Get historical data for multiple tickers
tech_history <- get_tickers_history(tech_tickers, period = "1y")
} # }
