UNICORN Binance Trailing Stop Loss

Description | Smart Entry | Installation | Documentation | Examples | Change Log | Wiki | Social | Notifications | Bugs | Contributing | Disclaimer | Commercial Support

A Python library by LUCIT with a command line interface for a trailing stop loss and smart entry on the Binance exchange.

Please read carefully all provided documentation, our disclaimer and look in the issues about known problems before using this tool - you use it at your own risk!

If you put this engine on a market, you should stop trading manually on this market yourself!

How to start the trailing stop loss engine:

from unicorn_binance_trailing_stop_loss import BinanceTrailingStopLossManager

def callback_error(msg):

def callback_finished(msg):
def callback_partially_filled(msg):
ubtsl = BinanceTrailingStopLossManager(callback_error=callback_error,

Stop the engine:


Discover more possibilities.

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

$ ubtsl --profile BTCUSDT_SELL --stoplosslimit 0.5%

Read about the CLI usage.


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 trail jump-in-and-trail
Binance yes no
Binance Testnet yes no
Binance Futures yes yes
Binance Isolated Margin yes yes (experimental)
Binance Margin yes yes
  • 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.

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 3.7 and runs smoothly up to and including Python 3.12.

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, but only in the latest version!

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.


pip install unicorn-binance-trailing-stop-loss


pip install unicorn-binance-trailing-stop-loss --upgrade

A Conda Package of the latest version with conda from Anaconda

The unicorn-binance-trailing-stop-loss package is also available as a Cython version for the linux-64, osx-64 and win-64 architectures with Conda through the lucit channel.

For optimal compatibility and performance, it is recommended to source the necessary dependencies from the conda-forge channel.


conda config --add channels conda-forge
conda config --add channels lucit
conda install -c lucit unicorn-binance-trailing-stop-loss


conda update -c lucit unicorn-binance-trailing-stop-loss

From source of the latest release with PIP from GitHub

Linux, macOS, ...

Run in bash:

pip install$(curl -s | grep -oP '"tag_name": "\K(.*)(?=")').tar.gz --upgrade


Use the below command with the version (such as 1.1.0) you determined here:

pip install --upgrade

From the latest source (dev-stage) with PIP from GitHub

This is not a release version and can not be considered to be stable!

pip install --upgrade

Download the latest release or the current master branch and use:

  • ./environment.yml
  • ./pyproject.toml
  • ./requirements.txt
  • ./
