What is Binance WebSocket?

Binance WebSocket is a real-time data streaming API provided by Binance. It allows users to receive real-time market data, such as price and volume, as well as real-time updates on orders, trades, and account balances. The Binance WebSocket API uses the WebSocket protocol, which is a communication protocol that provides full-duplex communication channels over a single TCP connection.

What is Python?

Python is a high-level programming language that is widely used in various fields, such as web development, data analysis, machine learning, and artificial intelligence. Python is known for its simplicity, readability, and ease of use. It has a large and active community of developers who contribute to its open-source libraries and frameworks.

What is Binance WebSocket Python?

Binance WebSocket Python is a Python library that provides an easy-to-use interface for accessing Binance WebSocket API. It allows developers to subscribe to real-time market data and execute trades programmatically. Binance WebSocket Python is built on top of the popular Python WebSocket library, which provides a simple interface for working with WebSocket protocols.

How to Install Binance WebSocket Python?

Installing Binance WebSocket Python is easy using pip, a package manager for Python. Open your terminal or command prompt and run the following command:

pip install binance-connector-websocket

How to Use Binance WebSocket Python?

Using Binance WebSocket Python is straightforward. Here is an example that subscribes to real-time Bitcoin price updates:

from binance.websocket.spot.websocket_client import SpotWebsocketClientdef btc_price_callback(msg):print("BTC price: ", msg['data']['c'])
client = SpotWebsocketClient()client.start()client.subscribe_ticker_event(symbol='btcusdt', callback=btc_price_callback)

This code creates a WebSocket client using the SpotWebsocketClient class. It then subscribes to the ticker event for the BTC/USDT trading pair using the subscribe_ticker_event method. When a new ticker event is received, the btc_price_callback function is called, which prints the current BTC price.

What are Some Other Examples of Using Binance WebSocket Python?

There are many other ways to use Binance WebSocket Python. Here are some examples:

Real-time order book updates

from binance.websocket.spot.websocket_client import SpotWebsocketClientdef order_book_callback(msg):print("Order book: ", msg['data'])
client = SpotWebsocketClient()client.start()client.subscribe_order_book_event(symbol='btcusdt', callback=order_book_callback)

Real-time trades updates

from binance.websocket.spot.websocket_client import SpotWebsocketClientdef trades_callback(msg):print("Trades: ", msg['data'])
client = SpotWebsocketClient()client.start()client.subscribe_trade_event(symbol='btcusdt', callback=trades_callback)

Real-time K-line updates

from binance.websocket.spot.websocket_client import SpotWebsocketClientdef kline_callback(msg):print("K-line: ", msg['data'])
client = SpotWebsocketClient()client.start()client.subscribe_kline_event(symbol='btcusdt', interval='1m', callback=kline_callback)
