Bybit provides a robust API that allows developers to create automated trading bots for executing trades efficiently. This guide will walk you through the steps of connecting to Bybit’s API and programming a trading bot.

1. Understanding Bybit API

Bybit API offers RESTful and WebSocket endpoints for accessing market data, managing orders, and monitoring account activity. There are three main types of APIs:

• Public API: Access to market data, such as order books and recent trades.
• Private API: Requires authentication and allows managing orders, positions, and funds.
• WebSocket API: Real-time data streaming for faster execution.

To get started, you need an API key from your Bybit account.

2. Creating an API Key on Bybit

Step 1: Log in to Bybit

Go to Bybit’s official website and log in to your account.

Step 2: Navigate to API Management

• Click on your profile icon and select “API Management”.
• Click “Create New Key”.

Step 3: Set API Permissions

• Choose “System-generated API Key”.
• Assign permissions based on your trading bot’s requirements (Read, Write, Trade, Withdraw).
• Copy the API Key and Secret Key (store them securely).

3. Connecting to Bybit API Using Python

Install Dependencies

pip install requests

Example: Fetching Market Data

import requests

url = "https://api.bybit.com/v2/public/tickers"
response = requests.get(url)
data = response.json()
print(data)

Example: Placing an Order

import time
import hmac
import hashlib
import requests

api_key = "YOUR_API_KEY"
api_secret = "YOUR_API_SECRET"
timestamp = str(int(time.time() * 1000))
params = f"api_key={api_key}&symbol=BTCUSDT&side=Buy&order_type=Market&qty=0.01&time_in_force=GoodTillCancel&timestamp={timestamp}"
signature = hmac.new(api_secret.encode(), params.encode(), hashlib.sha256).hexdigest()

url = "https://api.bybit.com/v2/private/order/create"
headers = {"Content-Type": "application/x-www-form-urlencoded"}
response = requests.post(url, data=params + f"&sign={signature}", headers=headers)
print(response.json())

4. Building a Simple Trading Bot

Steps to Automate Trading

1. Retrieve market data to determine trade signals.
2. Implement a trading strategy, such as moving averages or RSI.
3. Execute trades using the Bybit API.
4. Monitor orders and manage risk.

Example: Simple RSI-based Trading Bot

import requests

def get_price():
    url = "https://api.bybit.com/v2/public/tickers?symbol=BTCUSDT"
    response = requests.get(url)
    return float(response.json()["result"]["last_price"])

# Implement RSI or Moving Average strategy here

# Place orders when the condition is met
# execute_trade("Buy", 0.01)

5. Security Best Practices

• Use Read-Only API keys for market data.
• Restrict IP access to trusted addresses.
• Never expose your API key in public repositories.
• Enable Two-Factor Authentication (2FA) for added security.
