Building an Automated Crypto Trading Bot using Coinbase API

Cryptocurrency trading has become increasingly popular, and many investors are exploring ways to automate their trading strategies. In this article, we'll guide you through the process of creating a simple yet powerful trading bot using the Coinbase API, allowing you to execute trades based on real-time market data.

Overview

This trading bot is designed to automatically buy $20 worth of the newest top 5 cryptocurrencies every 30 minutes. After this period, it evaluates the profitability of each investment, sells the least profitable asset, and buys the latest top mover. The goal is to optimize your crypto portfolio dynamically.

Prerequisites

Before we dive into the installation and setup, make sure you have the following:

1. Coinbase Account: You'll need an active Coinbase account to access the API. If you don't have one, sign up here.
2. API Key and Secret: Generate an API key and secret from your Coinbase account. Follow Coinbase's official guide here for instructions.
3. Python Installation: Ensure you have Python installed on your machine. You can download it from here.

Setting Up the Trading Bot

1. Clone the Repository: Open a terminal and run the following command to clone the GitHub repository:

            git clone https://github.com/yourusername/coinbase-trading-bot.git
cd coinbase-trading-bot
            

2. Install Dependencies: Install the required Python packages by running:

            pip install requests
pip install coinbase
            

3. Configure the Bot: Open the config.py file and replace the placeholder values with your Coinbase API key and secret.
4. Run the Bot: Execute the bot script by running:

            python trading_bot.py

The bot will now start making automated trades based on the defined strategy.

How the Bot Works

The trading bot follows a simple strategy:

• Buy Phase: It buys $20 worth of the newest top 5 cryptocurrencies.
• Evaluation Phase: After 30 minutes, it evaluates the profitability of each investment.
• Sell Phase: The least profitable cryptocurrency is sold.
• Reinvestment Phase: The bot then buys the newest top mover to optimize the portfolio.

Benefits of the Trading Bot

1. Automation: The bot eliminates the need for manual trading, saving you time and effort.
2. Dynamic Portfolio Optimization: It continuously adapts your portfolio based on the latest market trends.
3. Risk Management: The script includes error handling to ensure safe execution and protect your investments.

Risks and Considerations

• Market Volatility: Cryptocurrency markets are highly volatile. Be aware of potential risks and only invest what you can afford to lose.
• API Security: Keep your API key and secret secure. Never share them publicly.

Demo Script

Below is a simplified version of the trading bot script for demonstration purposes. This script assumes you have already set up the required API key and secret in the config.py file.

        import time

import json

from coinbase.wallet.client import Client

from config import API_KEY, API_SECRET

# Initialize Coinbase client

client = Client(API_KEY, API_SECRET)

def get_top_movers():

    # Retrieve the top 5 cryptocurrencies

    currencies = client.get_currencies()

    top_movers = currencies[:5]

    return top_movers

def buy_crypto(currency, amount):

    # Place a buy order for the specified cryptocurrency

    buy_price = client.get_buy_price(currency_pair=f"{currency}-USD").amount

    buy_order = client.buy(account_id="your_account_id", amount=amount, currency=currency, commit=False)

    buy_order.commit()

    print(f"Successfully bought {amount} {currency} at {buy_price} USD each.")

def sell_crypto(account_id, currency, amount):

    # Place a sell order for the specified cryptocurrency

    sell_price = client.get_sell_price(currency_pair=f"{currency}-USD").amount

    sell_order = client.sell(account_id=account_id, amount=amount, currency=currency, commit=False)

    sell_order.commit()

    print(f"Successfully sold {amount} {currency} at {sell_price} USD each.")

# Main trading loop

while True:

    try:

        # Buy Phase

        print("\n=== Buy Phase ===")

        top_movers = get_top_movers()

        for currency in top_movers:

            buy_crypto(currency.id, 4)

        # Evaluation Phase

        print("\n=== Evaluation Phase ===")

        time.sleep(1800)  # Wait for 30 minutes

        # Sell Phase

        print("\n=== Sell Phase ===")

        account_id = "your_account_id"

        least_profitable_currency = min(top_movers, key=lambda x: x.price)

        sell_crypto(account_id, least_profitable_currency.id, 4)

        # Reinvestment Phase

        print("\n=== Reinvestment Phase ===")

        new_top_mover = get_top_movers()[0]

        buy_crypto(new_top_mover.id, 4)

        # Repeat the trading cycle

        print("\n=== Next Cycle ===")

    except Exception as e:

        print(f"Error: {e}")

        time.sleep(60)  # Wait for 1 minute before retrying
