Provides a summary of the aggregate orders posted by OANDA fxTrade clients at each price level.

Usage

oanda_orders(instrument, time, server, apikey)

Arguments

instrument

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.

time

(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.

server

(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.

apikey

(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.

Value

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.

Details

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.

For further details please refer to the OANDA fxTrade API vignette by calling: vignette("xoanda", package = "ichimoku").

Examples
