Details

Within an open--high--low--close bar chart, each bar represents price information for the time interval between the open and the close price. The left tick for each bar indicates the open price for the time interval. The right tick indicates the closing price for the time interval. The vertical length of the bar represents the price range for the time interval.

Examples
# Plot OHLC bar chart for the last `nDays' days of the instrument `instrument'

nDays <- 50
instrument <- "^spc"

start <- strftime(as.POSIXlt(Sys.time() - nDays*24*3600), format="%Y-%m-%d") 
end <- strftime(as.POSIXlt(Sys.time()), format = "%Y-%m-%d") 
x <- get.hist.quote(instrument = instrument, start = start, end = end)
