ichimoku contains an interface, or binding for the R language, to the OANDA fxTrade API.
OANDA is a primary source of foreign exchange data used by corporations and governments around the world. The API can be used for retrieving historical and live streaming price data for major currencies, metals, commodities, government bonds and stock indices.
As an example of the financial data that is available: OHLC pricing data can be obtained for major forex pairs from the start of 2005 with granularity ranging from 5 seconds to monthly. For the total list of over 120 covered instruments please refer to the Available Instruments section below.
Please note that ‘OANDA’ and ‘fxTrade’ are trademarks owned by OANDA Corporation, an entity unaffiliated with the ichimoku package.
Registering for a ‘demo’ or ‘practice’ account is entirely free at the time of writing and provides full access to the API. For registering an account, the following URL may be used: https://www.oanda.com/forex-trading/.
After successful registration, a link can be found on your OANDA fxTrade account profile page ‘Manage API Access’ (My Account -> My Services -> Manage API Access). From there, a personal access token to use with the OANDA API can be generated, as well as revoked. This access token will enable all the OANDA functions in this package.
If the ‘keyring’ package is installed, the OANDA API key (personal access token) can be set once and saved in your system credential store by using
oanda_set_key(). This will enable it to be retrieved automatically for all subsequent sessions.
Separate keys can be set for practice and live accounts; please choose the correct account type when prompted.
If an access token is revoked and re-generated, please remember to set the API key again through the
If you are using an access token for a live (real money) account, you will want to call
oanda_switch() at the beginning of each session; this switches the default server from the practice server to the live server. Settings will only persist until the end of the session.
library(ichimoku) oanda_switch() #> Default OANDA server switched to 'live'
Note: this package only contains functions for retrieving available instruments and price data. It does not contain code to implement any trading capability whatsoever. Please be aware however, that a personal access token can be used (outside of this package) for all operations on your account including placing orders and trades, and appropriate precautions should be taken when using your live account token.
All of the OANDA functions in the package are prefixed by ‘oanda’ for clarity.
Functions may be called interactively without any arguments, e.g.
oanda_view(), in which case you will be further prompted to enter required arguments; as opposed to when specifying such arguments normally, these should be entered unquoted i.e. without any surrounding ““.
For all functions, the ‘instrument’ argument is case-insensitive and the delimiter can be either ’_’ or ‘-’, such that both
oanda("usd-jpy") would be acceptable.
Retrieve pricing data from the OANDA fxTrade API.
The arguments to the function are phrased identically to that of the API itself where relevant:
instrumentstring 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
granularity[default “D”] the granularity of the price data to fetch, one of “M”, “W”, “D”, “H12”, “H8”, “H6”, “H4”, “H3”, “H2”, “H1”, “M30”, “M15”, “M10”, “M5”, “M4”, “M2”, “M1”, “S30”, “S15”, “S10”, “S5”
count(optional) the number of periods to return. The API supports a maximum of 5000 for each individual request, and defaults to 500 if not specified. If both ‘from’ and ‘to’ are specified, ‘count’ is ignored, as the time range combined with ‘granularity’ will determine the number of periods to return
from(optional) the start of the time range for which to fetch price data, for example “2020-02-01”
to(optional) the end of the time range for which to fetch price data, for example “2020-06-30”
price[default “M”] the pricing component, one of “M” (midpoint), “B” (bid) or “A” (ask)
server(optional) Specify the “practice” or “live” server according to the account type held with OANDA. If not specified, will default to “practice”, unless this has been changed by
apikey(optional) string containing the OANDA fxTrade API key (personal access token). Does not need to be specified if already stored by
oanda_set_key(). This argument is designed for specifying a function that returns such a string rather than the string itself, which could be potentially unsecure. This allows other packages that provide secure storage of secrets to be used if preferred over ‘keyring’
quietlyif set to TRUE, will suppress printing of output to the console and return quietly
Note: if both
to are specified and the request would result in over 5000 periods being returned, the function prompts the user to confirm if multiple requests should be submitted. Unless the user response is “n” or “no”, the data will proceed to be downloaded with rate limiting in place, and merged together into a single dataframe. The function is safe for use in non-interactive settings as in such cases the download will proceed automatically without prompting.
oanda("USD_JPY", count = 3, from = "2010-11-01", price = "B") #> time open high low close volume complete #> 1 2010-11-01 21:00:00 80.275 81.504 80.225 80.501 22291 TRUE #> 2 2010-11-02 21:00:00 80.504 80.956 80.460 80.617 13795 TRUE #> 3 2010-11-03 21:00:00 80.632 81.585 80.594 81.069 22204 TRUE
The returned object is a dataframe with the following columns: ‘time’, ‘open’, ‘high’, ‘low’, ‘close’, ‘volume’ and ‘complete’.
volume should be used with caution as this reflects the trading volume registered by OANDA and may not be reflective of the broader market
complete indicates whether the data period is complete or not. If TRUE, the values are historical and not subject to change. If FALSE, the period is ongoing and the values reflect the current snapshot whilst final values may or may not differ
Important implementation notes:
Incorporates automatic adjustment of the timestamps to end of period, as is customary for financial data. This means that, for example, today’s pricing data (incomplete trading period) will have today’s date as would be expected. In contrast, the raw data from the API has a timestamp of the start of the period
The API data sometimes includes data for non-trading days with very low volumes. This is more common for older data and less so with more recent data. These may represent OTC trades that occurred over the OANDA platform, but nevertheless do not reflect market rates. These are automatically excluded from the data returned as they would otherwise produce spurious results used with
Create an updating real-time Ichimoku cloud chart. The refresh rate can be set for the chart to be updated down to every second. A plot of the ichimoku chart for the price data requested is output to the graphical device at each refresh interval.
The arguments are identical to
oanda() above with the addition of:
refresh[default 5] set the refresh rate of the chart in seconds, with a minimum of 1
...additional parameters passed onto
ichimoku()for calculating the ichimoku cloud or
autoplot()to set chart parameters
periods[default c(9L, 26L, 52L)] a vector defining the length of periods used for the cloud. This parameter should not normally be modified as using other values would be invalid in the context of traditional Ichimoku analysis
The arguments ‘from’ and ‘to’ are excluded as they are not relevant in this context.
# For a live Palladium price chart: oanda_chart("XPD_USD")
In RStudio, please switch to the plots plane to view the chart if not already in focus.
Note that the periods displayed on the chart will be fewer than the ‘count’ specified - using default cloud periods, the first 77 datapoints will be excluded. This is by design to ensure a full cloud is displayed (i.e. there are no missing values for any cloud lines at the start of the data). Please take this into account when setting the ‘count’ parameter.
On exit from the function, the ichimoku object underlying the chart will be returned (invisibly). This allows the data to be saved simply by assigning to an object.
# To access the data, simply assign the return value to an object: <- oanda_chart("XPD_USD")cloud
Create an interactive R Shiny session for working with real-time Ichimoku cloud charts. Provides a live analysis environment where parameters may be set interactively as required. The cursor infotip provides ready access to the data directly from the chart.
As all parameters can be set interactively in-app,
oanda_studio() may be called without specifying any arguments. Otherwise, parameters may be set beforehand in the same way as
The following additional parameters can be used to customise the behaviour of the Shiny environment:
new.process[default FALSE] if TRUE, will start the shiny session in a new R process, unblocking the current process and allowing continued use of the R console. Note that any stdout output from the new process is discarded but stderr output - messages, warnings and errors - are still sent through to the console
...additional arguments passed to
ichimoku()for calculating the ichimoku cloud,
autoplot()to set chart parameters, or the ‘options’ argument of
launch.browser[default TRUE] If TRUE, the system’s default web browser will be launched automatically after the app is started. The value of this argument can also be a function to call with the application’s URL. To use the default Shiny viewer in RStudio, please specify
The ichimoku object underlying the live cloud chart can be saved by selecting the Data Archive button.
This button uses
archive() to save the ichimoku object to disk. The filename will be of the form:
SUGAR_USD_D_A.rda. If confirmed, the file is saved to the browser’s default download location. Note that files with the same name are not overwritten but instead the filename is made unique.
To read back the file, use
# Supply the quoted file path / name, for example: <- archive("~/Downloads/SUGAR_USD_D_A.rda") cloud # Or alternatively, choose the saved file interactively using a system dialog: <- archive()cloud
Connect to the OANDA fxTrade streaming API and stream a list of prices generated by OANDA.
Requires a single argument, the ‘instrument’ to stream data for.
The ‘server’ and ‘apikey’ arguments are also available if required.
oanda_stream("UK10YB_GBP") #> Streaming data... Press 'Esc' to return #> type:PRICE time:2021-10-01T16:59:51.377314414Z #> bids: price:126.500 liquidity:10000 asks: price:126.540 liquidity:10000 #> closeoutBid:126.500 closeoutAsk:126.540 status:non-tradeable tradeable:false instrument:UK10YB_GBP
The stream output contains injected ANSI escape codes for formatting the console output, but otherwise represents the raw data feed without omission. As this is a raw feed, please note that the returned times are in UTC.
The following should be noted from the streaming API documentation:
A convenience function that outputs to the console the latest one-line price quote for an instrument.
The output format is as follows: instrument, timestamp, daily open, high, low and last prices, daily percentage change (from the open), and the pricing component (M for mid, B for bid, A for ask).
oanda_quote("USD_JPY") #> USD_JPY 2021-10-05 16:29:44 open: 110.931 high: 111.564 low: 110.871 last: 111.398 %chg: 0.421 M
Prints a snapshot overview of the selected market, showing the relative performance of all constituents.
The available markets are : ‘allfx’ for all available currencies, ‘bonds’ for government bonds, ‘commodities’ for commodities, ‘fx’ for major currency pairs, ‘metals’ for metals and ‘stocks’ for global stock markets. As partial matching is enabled, it is possible to type just the first letter e.g. ‘c’ for commodities.
The first retrieved timestamp and the pricing component are printed, followed by the dataframe showing similar data to
oanda_quote() for all instruments in the selected market. The data is ordered by the daily percentage change, from the most positive to the most negative.

Provides a summary of the aggregate positions held by OANDA fxTrade clients at each price level.
The data is returned as a dataframe, with parameters saved as attributes which can be viewed with
look(). A chart showing the percentage long and short positions at each price level is output to the graphical device.
Please note that this feature has been implemented by OANDA only for certain major currency pairs and should be considered experimental.

Note: the above table is saved as internal package data and used as a fallback if the API call fails. In such a case, a warning is issued once per session as subsequent calls will return the cached list.
The package retrieves the following once only during a session (the first time they are used) and caches the variables for further use:
If for any reason these become invalid or outdated, please re-load the package (or restart your R session) to enable these variables to be refreshed.
oanda_switch() will also clear all cached variables.
