Get historical candles

qt_api_symbols(symbol_names = "FB") %>% # this will get the symbol ID, which the candles api needs
  dplyr::pull(symbol_id) %>% 
  qt_api_candles(start_time = ymd(20180101), end_time = today(), interval = "OneWeek") %>% 
  ggplot(aes(x = end, y = close)) + 
  geom_line()

Getting started

Follow the Getting Started directions in the Questrade API documentation. Then run qt_init() to initialize questradeR. This will walk you through the process of getting and setting your API keys.

Security

Your API keys are never stored or accessed in plain text. questradeR uses the keyring package to store keys securely in your system’s credential store.
