OANDA REST-V20 API wrapper

OANDA REST-V20 API wrapper

The REST-V20 API specs are not completely released yet. Support for 'streaming', 'pricing history' and 'forex labs' endpoints will be integrated when OANDA releases the specs of those endpoints.

Status

• The endpoint specs known till this moment are covered by the code.
• Tests partially completed

Supported versions (passing the available tests) of Python:

	2.7	3.5
oanda-api-v20	YES	YES

Integration with Travis and Coveralls will follow.

Install

$ pip install git+https://github.com/hootnot/oanda-api-v20.git

If you want to run the tests, clone the repository:

$ git clone https://github.com/hootnot/oanda-api-v20
$ cd oanda-api-v20
# edit tests/account.txt and tests/token.txt ...
$ python setup.py test
$ python setup.py install

Design

I have choosen a different approach regarding the design of the new library versus the 'oandapy' library which is based on 'mixin' classes.

In the V20-library endpoints are represented as APIRequest objects derived from the APIRequest base class. Each endpoint group (accounts, trades, etc.) is represented by it's own class covering the functionality of all endpoints for that group.

The V20-library has a client 'API'-class which processes APIRequest objects.

So it comes down to:

import json
from oandapyV20 import API    # the client
import oandapyV20.endpoints.trades as trades

 access_token = "..."
 accountID = "..."
 client = API(access_token=access_token)

# request trades list
r = trades.Trades(accountID, op=trades.TRADE_LIST)
rv = client.request(r)
print("RESPONSE:\n{}".format(json.dumps(rv, indent=2)))

Processing series of requests is also possible now by storing different requests in an array or from some 'request-factory' class. Below an array example:

import json
from oandapyV20 import API    # the client
import oandapyV20.endpoints.accounts as accounts
import oandapyV20.endpoints.trades as trades

access_token = "..."
accountID = "..."
client = API(access_token=access_token)

# list of requests
lor = []
# request trades list
lor.append(trades.Trades(accountID, op=trades.TRADE_LIST))
# request accounts list
lor.append(accounts.Accounts(op=accounts.ACCOUNT_LIST))


for r in lor:
    rv = client.request(r)
    # put request and response in 1 JSON structure
    print("{}".format(json.dumps({"request": "{}".format(r),
                                  "response": rv}, indent=2)))

Output
