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.
unicorn_fied_stream_data = UnicornFy.binance_com_websocket(data)
or
ubwa.create_stream(['trade'], ['btcusdt'], output="UnicornFy")
markets =
channels =
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)
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.get_server_time(return_response=True)
print(f"Binance serverTime: {response['result']['serverTime']}")
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!
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()
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")
time.sleep(2)
print(f"Waiting 5 seconds and then stop the stream ...")
time.sleep(5)
Discover even more possibilities, use this script to stream everything from "binance.com" or try our examples!
This should be known by everyone using this lib:
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 apikey and apisecret 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.
Fully managed websockets and 100% auto-reconnect! Also handles maintenance windows!
No memory leaks from Python version 3.8 to 3.12!
The full UBS stack is delivered as a compiled C extension for maximum performance.
Support for Binance Websocket API, send requests like createorder, cancelopen_orders and many more directly over websocket!

Streams are processing asynchronous/concurrent (Python asyncio) and each stream is started in a separate thread, so
you don't need to deal with asyncio in your code! But you can consume with
await
, if you want!
Supports subscribe/unsubscribe on all exchanges! (Take a look to the max supported subscriptions per stream in the endpoint configuration overview!)
UNICORN Binance WebSocket API respects Binance's API guidelines and protects you from avoidable reconnects and bans.
Support for multiple private !userData streams with different api_key and api_secret.
(examplemultipleuserdata_streams.py)
Pick up the received data from the stream_buffer (FIFO or LIFO) -
if you can not store your data in cause of a temporary technical issue, you can
kick back the data to the stream_buffer
which stores the receives in the RAM till you are able to process the data in the normal way again.
Learn more!
Use separate stream_buffers for
specific streams
or
users!
Watch the stream_signals to receive CONNECT, FIRST_RECEIVED_DATA, DISCONNECT, STOP and
STREAM_UNREPAIRABLE signals from your streams! Learn more!
Get the received data unchanged as received, as Python dictionary or converted with
UnicornFy into well-formed Python dictionaries. Use the output
parameter of
create_stream()
to control the output format.

get_stream_info().
Available as a package via pip and conda as precompiled C extension with stub files for improved Intellisense
functions and source code for easier debugging of the source code. To the installation.
Nice to use with iPython:
"IPython (Interactive Python) is a command shell for interactive computing that offers introspection,
rich media, shell syntax, tab completion, and history."
(exampleinteractivemode.py)
Also, nice to use with the Jupyter Notebook :)
Monitoring API service
and a check_command

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.
