A simple framework for bootstrapping your Crypto Trading Bots

Trading Bots 🤖

A simple framework for bootstrapping your Crypto Trading Bots on Python 3.6+

Disclaimer: Still at an early stage of development. Rapidly evolving APIs.

Trading-Bots is a general purpose mini-framework for developing an algorithmic trading bot on crypto currencies, thus it makes no assumption of your trading goals.

Installation

Requirements

• macOS, Windows or Linux
• Python 3.6 or 3.7

To install Trading-Bots, simply use poetry (or pip, of course):

poetry add trading-bots

Remember to activate the virtual environment

poetry shell

Getting started

Let's learn by example creating a simple bot that fetches your Bitcoin balance on Buda.com!

We'll assume you have Trading-Bots installed already, and your virtual environment is active.

Create a project

If this is your first time, you’ll have to take care of some initial setup. Namely, you’ll need to auto-generate some code that establishes a Trading-Bots project.

From the command line, cd into a directory where you’d like to store your bots, then run the following command:

bots-admin startproject

TRADING BOTS 🤖
===============

Name [MyAwesomeProject]: MyProject
Directory [.]: .

This will create a my_project directory in your current directory.

Let’s look at what startproject created:

root/
    bots.py
    secrets.yml
    settings.yml
    my_project/
        __init__.py

These files are:

• The outer root/ directory is just a container for your project. Its name doesn't matter to Trading-Bots; you can rename it to anything you like.
• bots.py: A handy CLI that lets you interact with this Trading-Bots project in various ways.
• secrets.yml: A configuration file to store your project secrets like API keys and wallets DON'T SHARE YOUR SECRETS WITH ANYONE!
• settings.yml: Global settings for this project.
• The inner my_project/ directory is the actual Python package for your project.
• my_project/__init__.py: An empty file that tells Python that this directory should be considered a Python package.

Create a new bot

Now that your "project" is set up, you're set to start doing work.

Let's create a simple bot that fetches your Bitcoin balance on Buda.com!

Each bot you write in Trading-Bots consists of a Python package that follows a certain convention. Trading-Bots comes with a utility that automatically generates the basic directory structure of a bot, so you can focus on writing code rather than creating directories.

Your bots can live anywhere on your Python path. In this tutorial, we’ll create our bot as a submodule of my_project.

To create your bot, make sure you're in the same directory as bots.py and type this command:

python bots.py createbot

TRADING BOTS 🤖
===============

Name [MyAwesomeBot]: MyBot
Directory (your projects dir): my_project

That’ll create a directory my_bot, which is laid out like this:

my_bot/
    __init__.py
    bot.py
    configs/
        default.yml

This directory structure will house the MyBot bot.

You'll also have to "install" your new bot, by adding it to the project's settings.yml file.

settings.yml

installed_bots:
  - my_project.my_bot.bot.MyBot  

Configure you Buda.com account's API_KEY and API_SECRET onto secrets.yml credentials:

You can request your API credentials on you account's profile on Buda.com

secrets.yml

credentials:
  Buda:
    key: MY_API_KEY
    secret: MY_API_SECRET

Write yout first Bot logic

Now let's write the code to fetch the Bitcoin balance on Buda.com implementing the Bot's algorithm. The Bot's logic resides in the my_project/my_bot/bot.py module created by the createbot command:

my_project/my_bot/bot.py

# Base class that all Bots must inherit from
from trading_bots.bots import Bot

# The settings module contains all values from settings.yml and secrets.yml
from trading_bots.conf import settings

# API Wrapper for Buda.com
from trading_api_wrappers import Buda


class MyBot(Bot):
    # The label is a unique identifier you assign to your bot on Trading-Bots
    label = 'MyBot'

    def _setup(self, config):
        # Get API_KEY and API_SECRET from credentials
        credentials = settings.credentials['Buda']
        key = credentials['key']
        secret = credentials['secret']

        # Initialize a Buda Auth client
        self.buda = Buda.Auth(key, secret)

    def _algorithm(self):
        # Fetch the Bitcoin balance from Buda.com
        balance = self.buda.balance('BTC')

        # Log the Bitcoin balance
        self.log.info(f'I have {balance.amount.amount} BTC')

    def _abort(self):
        # Abort logic, runs on exception
        self.log.error(f'Something went wrong with MyBot!')

Bot execution

Run the bot!

python bots.py run MyBot

Add more features

We can make our Bot a little more modular, let's now fetch our Ethereum balance adding a currency key on MyBot default config file on my_project/my_bot/configs/default.yml:

my_project/my_bot/configs/default.yml

currency: ETH

Now use the new currency config on MyBot by modifying the Bot's logic:

my_project/my_bot/bot.py

from trading_bots.bots import Bot
from trading_bots.conf import settings

from trading_api_wrappers import Buda


class MyBot(Bot):
    label = 'MyBot'

    def _setup(self, config):
        # Get currency from config
        self.currency = config['currency']

        # Get API_KEY and API_SECRET from credentials
        credentials = settings.credentials['Buda']
        key = credentials['key']
        secret = credentials['secret']

        # Initialize a Buda Auth client
        self.buda = Buda.Auth(key, secret)

    def _algorithm(self):
        # Fetch the currency balance from Buda.com
        balance = self.buda.balance(self.currency)

        # Log the currency balance
        self.log.info(f'I have {balance.amount.amount} {self.currency}')

    def _abort(self):
        # Abort logic, runs on exception
        self.log.error(f'Something went wrong with MyBot!')
