Provides a summary of the aggregate orders posted by OANDA fxTrade clients at each price level.
oanda_orders(instrument, time, server, apikey)string containing the base currency and quote currency
delimited by '_' or '-' (e.g. "USD_JPY" or "usd-jpy"). Use the
oanda_instruments function to return a list of all valid
instruments.
(optional) the time for which to retrieve the order book, in a
format convertible to POSIXct by as.POSIXct(). If not specified,
the most recent order book will be retrieved.
(optional) specify the "practice" or "live" server according to
the account type held. If not specified, will default to "practice", unless
this has been changed by oanda_switch.
(optional) string containing the OANDA fxTrade API key (personal
access token), or function that returns this string. Does not need to be
specified if already stored as the environment variable
OANDA_API_KEY or by oanda_set_key. Can also be
entered interactively if not specified.
Invisibly, a data frame of the order book with parameters saved as attributes. A chart showing the percentage long and short orders at each price level is output to the graphical device.
This feature has been implemented by OANDA only for certain major currency pairs and should be considered experimental.
Note: as certain orders are placed far from the market price, only the interquartile range of order levels is shown on the chart. The returned data frame does however contain the entire order book.
