Receive Data from Binance WebSockets

Create a multiplex websocket connection to Binance with a stream_buffer with just 3 lines of code:

from unicorn_binance_websocket_api import BinanceWebSocketApiManager

ubwa = BinanceWebSocketApiManager(exchange="binance.com")
ubwa.create_stream(channels=['trade', 'kline_1m'], markets=['btcusdt', 'bnbbtc', 'ethbtc'])

And 4 more lines to print the receives:

while True:
    oldest_data_from_stream_buffer = ubwa.pop_stream_data_from_stream_buffer()
    if oldest_data_from_stream_buffer:
        print(oldest_data_from_stream_buffer)

Or with a callback function just do:

from unicorn_binance_websocket_api import BinanceWebSocketApiManager


def process_new_receives(stream_data):
    print(str(stream_data))


ubwa = BinanceWebSocketApiManager(exchange="binance.com")
ubwa.create_stream(channels=['trade', 'kline_1m'], 
                   markets=['btcusdt', 'bnbbtc', 'ethbtc'], 
                   process_stream_data=process_new_receives)

Basically that’s it, but there are more options.

Convert received raw webstream data into well-formed Python dictionaries with UnicornFy:

unicorn_fied_stream_data = UnicornFy.binance_com_websocket(oldest_data_from_stream_buffer)

or

ubwa.create_stream(['trade'], ['btcusdt'], output="UnicornFy")

Subscribe / unsubscribe new markets and channels:

markets = ['engbtc', 'zileth']
channels = ['kline_5m', 'kline_15m', 'kline_30m', 'kline_1h', 'kline_12h', 'depth5']

ubwa.subscribe_to_stream(stream_id=stream_id, channels=channels, markets=markets)

ubwa.unsubscribe_from_stream(stream_id=stream_id, markets=markets)

ubwa.unsubscribe_from_stream(stream_id=stream_id, channels=channels)

Send Requests to Binance WebSocket API

Place orders, cancel orders or send other requests via WebSocket:

from unicorn_binance_websocket_api import BinanceWebSocketApiManager


def process_api_responses(stream_data):
    print(str(stream_data))


api_key = "YOUR_BINANCE_API_KEY"
api_secret = "YOUR_BINANCE_API_SECRET"


ubwa = BinanceWebSocketApiManager(exchange="binance.com")
api_stream = ubwa.create_stream(api=True, 
                                api_key=api_key, 
                                api_secret=api_secret,
                                process_stream_data=process_api_responses)
                                
orig_client_order_id = ubwa.api.create_order(order_type="LIMIT", 
                                             price=1.1, 
                                             quantity=15.0, 
                                             side="SELL", 
                                             symbol="BUSDUSDT")
ubwa.api.cancel_order(orig_client_order_id=orig_client_order_id, symbol="BUSDUSDT")                                             

Here you can find a complete guide on how to process requests via the Binance WebSocket API!

Stop ubwa after usage to avoid memory leaks

ubwa.stop_manager()

Description

The Python package UNICORN Binance WebSocket API provides an API to the Binance Websocket API`s of Binance (+Testnet), Binance Margin (+Testnet), Binance Isolated Margin (+Testnet), Binance Futures (+Testnet), Binance COIN-M Futures, Binance US, Binance TR, Binance DEX and Binance DEX Testnet and supports sending requests to the Binance Websocket API and the streaming of all public streams like trade, kline, ticker, depth, bookTicker, forceOrder, compositeIndex, blockheight etc. and also all private userData streams which needs to be used with a valid api_key and api_secret from the Binance Exchange www.binance.com, testnet.binance.vision or www.binance.us - for the DEX you need a user address from www.binance.org or testnet.binance.org and you can get funds for the testnet.

Use the UNICORN Binance REST API in combination.

Installation and Upgrade

The module requires Python 3.7 or above, as it depends on Pythons latest asyncio features for asynchronous/concurrent processing.

For the PyPy interpreter we offer packages only from Python version 3.9 and higher.

Anaconda packages are available from Python version 3.8 and higher.

The current dependencies are listed here.

If you run into errors during the installation take a look here.

A Cython binary, PyPy or source code based CPython wheel of the latest version with pip from PyPI

Our Cython and PyPy Wheels are available on PyPI, these wheels offer significant advantages for Python developers:

  • Performance Boost with Cython Wheels: Cython is a programming language that supplements Python with static typing and C-level performance. By compiling Python code into C, Cython Wheels can significantly enhance the execution speed of Python code, especially in computationally intensive tasks. This means faster runtimes and more efficient processing for users of our package.

  • PyPy Wheels for Enhanced Efficiency: PyPy is an alternative Python interpreter known for its speed and efficiency. It uses Just-In-Time (JIT) compilation, which can dramatically improve the performance of Python code. Our PyPy Wheels are tailored for compatibility with PyPy, allowing users to leverage this speed advantage seamlessly.

Both Cython and PyPy Wheels on PyPI make the installation process simpler and more straightforward. They ensure that you get the optimized version of our package with minimal setup, allowing you to focus on development rather than configuration.

SOCKS5 Proxy / Geoblocking

We would like to explicitly point out that in our opinion US citizens are exclusively authorized to trade on Binance.US and that this restriction must not be circumvented!

The purpose of supporting a SOCKS5 proxy in the UNICORN Binance Suite and its modules is to allow non-US citizens to use US services. For example, GitHub actions with UBS will not work without a SOCKS5 proxy, as they will inevitably run on servers in the US and be blocked by Binance.com. Moreover, it also seems justified that traders, data scientists and companies from the US analyze binance.com market data - as long as they do not trade there.
