Receive Data from Bybit WebSockets

Create a multiplex websocket connection to Bybit with a `stream_buffer` with just 3 lines of code

from unicorn_bybit_websocket_api import BybitWebSocketApiManager

bybit_wsm = BybitWebSocketApiManager(exchange="bybit.com")
bybit_wsm.create_stream(endpoint="public/linear", channels=['kline.1'], markets=['btcusdt', 'ethusdt'])

And 4 more lines to print out the data

while True:
    oldest_data_from_stream_buffer = bybit_wsm.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_bybit_websocket_api import BybitWebSocketApiManager

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

bybit_wsm = BybitWebSocketApiManager(exchange="bybit.com")
bybit_wsm.create_stream(endpoint="public/linear", channels=['kline.1m'], 
                        markets=['btcusdt', 'ethusdt'], 
                        process_stream_data=process_new_receives)

Or with an async callback function just do

from unicorn_bybit_websocket_api import BybitWebSocketApiManager
import asyncio

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

bybit_wsm = BybitWebSocketApiManager()
bybit_wsm.create_stream(endpoint="public/linear", channels=['kline_1m'],
                        markets=['btcusdt', 'ethusdt'],
                        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_bybit_websocket_api import BybitWebSocketApiManager
import asyncio

async def main():
    async def process_asyncio_queue(stream_id=None):
        print(f"Start processing the data from stream '{bybit_wsm.get_stream_label(stream_id)}':")
        while bybit_wsm.is_stop_request(stream_id) is False:
            data = await bybit_wsm.get_stream_data_from_asyncio_queue(stream_id)
            print(data)
            bybit_wsm.asyncio_queue_task_done(stream_id)
    bybit_wsm.create_stream(endpoint="public/linear",
                            channels=['kline.1'],
                            markets=['btcusdt', 'ethusdt'],
                            stream_label="KLINE_1m",
                            process_asyncio_queue=process_asyncio_queue)
    while not bybit_wsm.is_manager_stopping():
            await asyncio.sleep(1)

with BybitWebSocketApiManager(exchange='bybit.com') as bybit_wsm:
    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.

Subscribe / unsubscribe new markets and channels

These functions are not ready! (Todo!)

Stop `bybit_wsm` after usage to avoid memory leaks

When you instantiate UNICORN Bybit Websocket API with with, bybit_wsm.stop_manager() is automatically executed upon exiting the with-block.

with BybitWebSocketApiManager() as bybit_wsm:
    bybit_wsm.create_stream(channels="kline.1", markets="btcusdt", stream_label="KLINE_1m")

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

bybit_wsm.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 Bybit 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_bybit_websocket_api import BybitWebSocketApiManager
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 '{bybit_wsm.get_stream_label(stream_id=stream_id)}': "
          f"{signal_type} - {stream_id} - {data_record} - {error_msg}")

with BybitWebSocketApiManager(process_stream_signals=process_stream_signals) as bybit_wsm:
    bybit_wsm.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)

Description

The Python package UNICORN Bybit WebSocket API provides an API to the Bybit Websocket API`s of Bybit (+Testnet).

What are the benefits of the UNICORN Bybit WebSocket API?

Fully managed websockets and 100% auto-reconnect! Also handles maintenance windows!
No memory leaks from Python version 3.7 to 3.12!
The full UTS stack is delivered as a compiled C extension for maximum performance.
Supported exchanges:

Exchange	Exchange string	WS	WS API
Bybit	`bybit.com`
Bybit Testnet	`bybit.com-testnet`

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 Bybit WebSocket API respects Bybit's API guidelines and protects you from avoidable reconnects and bans.
Support for multiple private !userData streams with different api_key and api_secret. (example_multiple_userdata_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.
Helpful management features like clear_asyncio_queue(), clear_stream_buffer(), get_bybit_api_status(), get_current_receiving_speed(), get_errors_from_endpoints(), get_limit_of_subscriptions_per_stream(), get_request_id(), get_result_by_request_id(), get_results_from_endpoints(), get_stream_buffer_length(), get_stream_info(), get_stream_list(), get_stream_id_by_label(), get_stream_statistic(), get_stream_subscriptions(), get_version(), is_update_available(), get_stream_data_from_asyncio_queue(), pop_stream_data_from_stream_buffer(), print_summary(), replace_stream(), set_stream_label(), set_ringbuffer_error_max_size(), subscribe_to_stream(), stop_stream(), unsubscribe_from_stream(), wait_till_stream_has_started() and many more! Explore them here.
Monitor the status of the created BybitWebSocketApiManager() instance within your code with get_monitoring_status_plain() and specific streams with 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.
Integration of test cases and examples.
Customizable base URL.

Socks5 Proxy support:

bybit_wsm = BybitWebSocketApiManager(exchange="bybit.com", socks5_proxy_server="127.0.0.1:9050")

Read the docs or this how to for more information or try example_socks5_proxy.py.

Excessively tested on Linux, Mac and Windows on x86, arm32, arm64, ...

If you like the project, please it on GitHub!

Installation and Upgrade

The module requires Python 3.7 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!
