Benefits

• A simple to use python wrapper for endpoints.-
• In about 10 minutes, you could be programmatically trading on one of the largest Bitcoin exchanges in the world!
• Do not worry about handling the nuances of the API with easy-to-use methods for every API endpoint.
• Gain an advantage in the market by getting under the hood of CB Adv to learn what and who is behind every tick.

Under Development

• Test Scripts
• Additional Functionality for the real-time order book
• MongoDB integration

Getting Started

This README is documentation on the syntax of the python client presented in this repository. See function docstrings for full syntax details.
This API attempts to present a clean interface to CB Advanced Trade, but in order to use it to its full potential, you must familiarize yourself with the official CB Advanced Trade documentation.

• You may manually install the project or use pip:

pip install cbadv (not yet added to PyPi)
#or
pip install git+git://github.com/kkuette/coinbaseadv-python.git

Client

import cbadv

API_KEY = ''
API_SECRET = ''

client = cbadv.Client(api_key=API_KEY, api_secret=API_SECRET)

or

import json
import cbadv

client = cbadv.Client(**json.load(open('path/to/credentials.json')))

Client Methods

All API endpoints are now Private. You must setup API access within your account settings.

• list_accounts

client.list_accounts()

• get_account

client.get_account("7d0f7d8e-dd34-4d9c-a846-06f431c381ba")

• buy & sell

# Buy 0.01 BTC @ 100 USD
client.buy(price='100.00', #USD
               size='0.01', #BTC
               order_type='limit',
               product_id='BTC-USD')

# Sell 0.01 BTC @ 200 USD
client.sell(price='200.00', #USD
                size='0.01', #BTC
                order_type='limit',
                product_id='BTC-USD')

# Limit order-specific method
client.place_limit_order(product_id='BTC-USD', 
                              side='buy', 
                              price='200.00', 
                              size='0.01')

# Place a market order by specifying amount of USD to use. 
# Alternatively, `size` could be used to specify quantity in BTC amount.
client.place_market_order(product_id='BTC-USD', 
                               side='buy', 
                               funds='100.00')

# Stop order. `funds` can be used instead of `size` here.
client.place_stop_order(product_id='BTC-USD', 
                              stop_type='loss', 
                              price='200.00', 
                              size='0.01')

• cancel_order

client.cancel_order("7d0f7d8e-dd34-4d9c-a846-06f431c381ba")

• list_orders

• list_products

client.list_products()

• get_product

client.get_product("BTC-USD")

• get_product_candles

• get_transactions_summary

client.get_transactions_summary()

WebsocketClient

If you would like to receive real-time market updates, you must subscribe to the websocket feed. Websockets are now available for Authenticated clients only. You must setup API access within your account settings.

Subscribe to a single product

import cbadv

# You need to provide api key and secret others parameters are optional
wsClient = cbadv.WebsocketClient(api_key, secret_key, url="wss://advanced-trade-ws.coinbase.com",
                                products="BTC-USD",
                                channels=["ticker"])
# Do other stuff...
wsClient.close()

Subscribe to multiple products

import cbadv
# You need to provide api key and secret others parameters are optional
wsClient = cbadv.WebsocketClient(api_key, secret_key, url="wss://advanced-trade-ws.coinbase.com",
                                products=["BTC-USD", "ETH-USD"],
                                channels=["ticker"])
# Do other stuff...
wsClient.close()

WebsocketClient Methods

The WebsocketClient subscribes in a separate thread upon initialization. There are three methods which you could overwrite (before initialization) so it can react to the data streaming in. The current client is a template used for illustration purposes only.

• onOpen - called once, immediately before the socket connection is made, this is where you want to add initial parameters.
• onMessage - called once for every message that arrives and accepts one argument that contains the message of dict type.
• on_close - called once after the websocket has been closed.
• close - call this method to close the websocket connection (do not overwrite).

import cbadv, time
class myWebsocketClient(cbadv.WebsocketClient):
    def __init__(self, apit_key, secret_key):
        super().__init__(api_key, secret_key)

    def on_open(self):
        self.url = "wss://advanced-trade-ws.coinbase.com"
        self.products = ["LTC-USD"]
        self.message_count = 0
        print("Lets count the messages!")
    def on_message(self, msg):
        self.message_count += 1
        if 'price' in msg and 'type' in msg:
            print ("Message type:", msg["type"],
                   "\t@ {:.3f}".format(float(msg["price"])))
    def on_close(self):
        print("-- Goodbye! --")

api_key = ''
secret_key = ''

wsClient = myWebsocketClient(api_key, secret_key)
#wsClient = myWebsocketClient(**json.load(open('path/to/credentials.json'))) # load from file
wsClient.start()
print(wsClient.url, wsClient.products)
while (wsClient.message_count < 500):
    print ("\nmessage_count =", "{} \n".format(wsClient.message_count))
    time.sleep(1)
wsClient.close()

Testing

A test suite is under development. Tests for the authenticated client require a set of sandbox API credentials. To provide them, rename api_config.json.example in the tests folder to api_config.json and edit the file accordingly. To run the tests, start in the project directory and run

python -m pytest

Real-time OrderBook

The OrderBook subscribes to a websocket and keeps a real-time record of the orderbook for the product_id input. Please provide your feedback for future improvements.

import cbadv, time, json

API_KEY = ''
API_SECRET = ''

order_book = cbadv.OrderBooks(api_key, api_secret, product_id=['BTC-USD', 'ETH-USD'])
order_book.start()
time.sleep(10)
order_book.close()

Testing

Unit tests are under development using the pytest framework. Contributions are welcome!

To run the full test suite, in the project directory run:

python -m pytest
