How to start the trailing stop loss engine:¶

from unicorn_binance_trailing_stop_loss import BinanceTrailingStopLossManager


def callback_error(msg):
    print(f"STOP LOSS ERROR - ENGINE IS SHUTTING DOWN! - {msg}")
    ubtsl.stop_manager()

def callback_finished(msg):
    print(f"STOP LOSS FINISHED - ENGINE IS SHUTTING DOWN! - {msg}")
    ubtsl.stop_manager()
    
def callback_partially_filled(msg):
    print(f"STOP LOSS PARTIALLY_FILLED - ENGINE IS STILL RUNNING! - {msg}")
    
ubtsl = BinanceTrailingStopLossManager(callback_error=callback_error,
                                       callback_finished=callback_finished,

Start the engine on the command line (Windows, Linux and Mac):¶

$ ubtsl --profile BTCUSDT_SELL --stoplosslimit 0.5%

Read about the CLI usage.

Description¶

The Python package UNICORN Binance Trailing Stop Loss provides a reuseable library and CLI interface.

After starting the engine, a stop/loss order is placed on Binance and trailed until it is completely fulfilled. If desired, a notification can be sent via email and Telegram afterward. Then it calls the function passed with the callback_finished parameter or on error it calls the function passed to callback_error.

Partially filled orders are currently not handled by the engine. If you want to react individually to this event, you can use the function provided to callback_partially_filled.

In addition, there is a smart entry option called jump-in-and-trail. This offers the possibility to buy spot, future and margin assets with a limit or market order and then to trail a stop/loss order until sold.

What are the benefits of the UNICORN Binance Trailing Stop Loss?¶

Using websockets for push notifications about price updates and order status updates. (Fast data transfer and low used API weight!)
Smart entry
Supported exchanges:

Exchange	Exchange string	jump-in-and-trail
Binance	`binance.com`
Binance Testnet	`binance.com-testnet`
Binance Futures	`binance.com-futures`
Binance Isolated Margin	`binance.com-isolated_margin`	(experimental)
Binance Margin	`binance.com-margin`

All parameters that expect numbers can be configured with fixed numerical values as well as with percentage values.
Integrated notification system (e-Mail and Telegram).
Test “notification”, “binance-connectivity” and “streams” without starting the engine.
Powered by UNICORN Binance REST API and UNICORN Binance WebSocket API.
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.
Well tested on Linux, Mac and Windows.

If you like the project, please it on GitHub!

Smart entry¶

This function is still in an experimental phase and only available for Isolated Margin.

Do a smart entry by using engine = 'jump-in-and-trail' and providing borrow_threshold.

By activating the jump-in-and-trail engine, the engine first buys the predefined asset amount and then trails them automatically.

Installation and Upgrade¶

The module requires Python 3.9 and runs smoothly up to and including Python 3.14.

PyPy wheels are available for all supported Python versions.

conda-forge note: Conda packages are provided for Python 3.10 – 3.14. Python 3.9 is not available on conda-forge — it was dropped from the global pinning after reaching end-of-life in October 2025. For Python 3.9, use pip install.

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 created, the Build and Publish GH+PyPi workflow spins up virtual Windows/Linux/Mac runners, compiles the Cython extensions, builds the wheels and publishes them on GitHub and PyPI. The conda-forge feedstock conda-forge/unicorn-binance-trailing-stop-loss-feedstock picks up the new PyPI release automatically and builds the Conda packages on its own infrastructure. 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.
