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 out the data

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)

Or with an async callback function just do

from unicorn_binance_websocket_api import BinanceWebSocketApiManager
import asyncio

async def process_new_receives(stream_data):
    print(stream_data)
    await asyncio.sleep(1)

ubwa = BinanceWebSocketApiManager()
ubwa.create_stream(channels=['trade', 'kline_1m'],
                   markets=['btcusdt', 'bnbbtc', 'ethbtc'],
                   process_stream_data_async=process_new_receives)

Or await the stream data in an asyncio coroutine

All the methods of data collection presented have their own advantages and disadvantages. However, this is the generally recommended method for processing data from streams.

from unicorn_binance_websocket_api import BinanceWebSocketApiManager
import asyncio

async def main():
    async def process_asyncio_queue(stream_id=None):
        print(f"Start processing the data from stream '{ubwa.get_stream_label(stream_id)}':")
        while ubwa.is_stop_request(stream_id) is False:
            data = await ubwa.get_stream_data_from_asyncio_queue(stream_id)
            print(data)
            ubwa.asyncio_queue_task_done(stream_id)
    ubwa.create_stream(channels=['trade'],
                       markets=['ethbtc', 'btcusdt'],
                       stream_label="TRADES",
                       process_asyncio_queue=process_asyncio_queue)
    while not ubwa.is_manager_stopping():
        await asyncio.sleep(1)

with BinanceWebSocketApiManager(exchange='binance.com') as ubwa:
    try:
        asyncio.run(main())
    except KeyboardInterrupt:
        print("\r\nGracefully stopping ...")
    except Exception as e:
        print(f"\r\nERROR: {e}\r\nGracefully stopping ...")

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

Convert received stream data into well-formed Python dictionaries with UnicornFy

unicorn_fied_stream_data = UnicornFy.binance_com_websocket(data)

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

api_key = "YOUR_BINANCE_API_KEY"
api_secret = "YOUR_BINANCE_API_SECRET"

async def process_api_responses(stream_id=None):
    while ubwa.is_stop_request(stream_id=stream_id) is False:
        data = await ubwa.get_stream_data_from_asyncio_queue(stream_id=stream_id)
        print(data)
        ubwa.asyncio_queue_task_done(stream_id=stream_id)

ubwa = BinanceWebSocketApiManager(exchange="binance.com")
api_stream = ubwa.create_stream(api=True,
                                api_key=api_key,
                                api_secret=api_secret,
                                output="UnicornFy",
                                process_asyncio_queue=process_api_responses)

response = ubwa.api.spot.get_server_time(return_response=True)
print(f"Binance serverTime: {response['result']['serverTime']}")

orig_client_order_id = ubwa.api.spot.create_order(order_type="LIMIT",
                                                  price = 1.1,
                                                  quantity = 15.0,
                                                  side = "SELL",
                                                  symbol = "BUSDUSDT")

ubwa.api.spot.cancel_order(orig_client_order_id=orig_client_order_id, symbol="BUSDUSDT")

All available methods:

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

When you instantiate UBWA with with, ubwa.stop_manager() is automatically executed upon exiting the with-block.

with BinanceWebSocketApiManager() as ubwa:
    ubwa.create_stream(channels="trade", markets="btcusdt", stream_label="TRADES")

Without with, you must explicitly execute ubwa.stop_manager() yourself.

ubwa.stop_manager()

stream_signals - know the state of your streams

Usually you want to know when a stream is working and when it is not. This can be useful to know that your own system is currently "blind" and you may want to close open positions to be on the safe side, know that indicators will now provide incorrect values or that you have to reload the missing data via REST as an alternative.

For this purpose, the UNICORN Binance WebSocket API provides so-called stream_signals, which are used to tell your code in real time when a stream is connected, when it received its first data record, when it was disconnected and stopped, and when the stream cannot be restored.

from unicorn_binance_websocket_api import BinanceWebSocketApiManager
import time

def process_stream_signals(signal_type=None, stream_id=None, data_record=None, error_msg=None):
    print(f"Received stream_signal for stream '{ubwa.get_stream_label(stream_id=stream_id)}': "
          f"{signal_type} - {stream_id} - {data_record} - {error_msg}")

with BinanceWebSocketApiManager(process_stream_signals=process_stream_signals) as ubwa:
    ubwa.create_stream(channels="trade", markets="btcusdt", stream_label="TRADES")
    print(f"Waiting a few seconds and then stopping the stream ...")
    time.sleep(7)

This should be known by everyone using this lib:

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 3.8 and runs smoothly up to and including Python 3.12.

Anaconda packages are available from Python version 3.8 and higher, but only in the latest version!

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

The current dependencies are listed here.

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

Packages are created automatically with GitHub Actions

When a new release is to be created, we start two GitHubActions:

Both start virtual Windows/Linux/Mac servers provided by GitHub in the cloud with preconfigured environments and create the respective compilations and stub files, pack them into wheels and conda packages and then publish them on GitHub, PYPI and Anaconda. This is a transparent method that makes it possible to trace the source code behind a compilation.

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.

On Raspberry Pi and other architectures for which there are no pre-compiled versions, the package can still be installed with PIP. PIP then compiles the package locally on the target system during installation. Please be patient, this may take some time!

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.
