Introduction
CCXT is a popular open-source library that provides a unified API for cryptocurrency exchanges. It makes it easy for developers to write software that interacts with multiple exchanges without having to learn the intricacies of each exchange’s API. One of the most useful features of CCXT is its WebSocket support, which enables real-time market data streaming. In this article, we will explore CCXT WebSocket in detail and learn how to use it to develop cryptocurrency trading applications.
What is WebSocket?
WebSocket is a protocol for real-time, bidirectional communication between a client and a server over a single TCP connection. It provides a persistent connection between the client and the server, allowing for real-time data transfer. WebSocket is designed to work over the same ports as HTTP and HTTPS (ports 80 and 443), making it easy to implement without firewall issues.
How does WebSocket work?
The WebSocket protocol starts with an HTTP handshake, where the client sends an HTTP request to the server. The server responds with an HTTP response, which includes a special header indicating that the server supports the WebSocket protocol. Once the handshake is complete, the client and server can start sending data to each other in real-time.
WebSocket uses a simple message-based framing protocol, where messages are sent as a series of frames. Each frame has a header and a payload. The header contains information such as the type of frame, the length of the payload, and whether the frame is the final frame in a message. The payload contains the actual data being sent.
WebSocket supports two types of messages: text and binary. Text messages are UTF-8 encoded strings, while binary messages can be any binary data. WebSocket also supports ping and pong messages, which can be used to check the health of the connection.
Why use WebSocket?
WebSocket provides several advantages over traditional HTTP polling or long-polling for real-time communication:
- Lower latency: WebSocket provides a persistent connection, eliminating the need for the overhead of establishing a new connection for each request.
- Better scalability: WebSocket allows for real-time communication with a large number of clients without overloading the server.
- Reduced network overhead: WebSocket uses a more efficient protocol than HTTP for real-time communication, reducing the amount of data sent over the network.
- Improved user experience: WebSocket enables real-time updates without the need for page refreshes or manual polling.
What is CCXT?
CCXT is a JavaScript / Python / PHP library for cryptocurrency trading and market analysis. It provides a unified API for interacting with multiple cryptocurrency exchanges, making it easy to write software that works with multiple exchanges. CCXT supports more than 120 exchanges, including popular ones such as Binance, Bitfinex, Coinbase Pro, and Kraken.
What is CCXT WebSocket?
CCXT WebSocket is a feature of the CCXT library that provides real-time market data streaming using the WebSocket protocol. It allows developers to receive real-time updates of market data, such as trades, order book changes, and ticker updates, from multiple exchanges using a unified API.
CCXT WebSocket is built on top of the popular WebSocket library ws and is designed to be easy to use and highly customizable. It provides a unified interface for subscribing to WebSocket channels and handling incoming messages, making it easy to write trading applications that work with multiple exchanges.
How to use CCXT WebSocket?
Using CCXT WebSocket is straightforward. First, you need to create an instance of the exchange you want to connect to, using the CCXT library. Then, you can use the exchange’s websocket method to connect to the exchange’s WebSocket API and start receiving real-time updates.
Here’s an example of how to connect to the Binance WebSocket API using CCXT WebSocket:
// Import CCXT libraryconst ccxt = require('ccxt');// Create an instance of the Binance exchangeconst binance = new ccxt.binance();
// Connect to the Binance WebSocket APIbinance.websocket('wss://stream.binance.com:9443/ws/!ticker@arr', (ticker) => {console.log(ticker); // Print ticker updates to the console});
This example connects to the Binance WebSocket API and subscribes to the !ticker@arr channel, which provides real-time ticker updates for all trading pairs on Binance. The websocket method takes a WebSocket URL and a callback function as arguments. The callback function is called every time a new message is received on the WebSocket connection.
CCXT WebSocket supports several other WebSocket channels, including trades, order book updates, and user account updates. You can find the complete list of supported channels in the CCXT documentation.
Customizing CCXT WebSocket
CCXT WebSocket is highly customizable, allowing you to configure various WebSocket options and customize the way messages are handled. Here are some of the customization options available in CCXT WebSocket:
- messageHandler: A function that is called every time a new message is received on the WebSocket connection. You can use this function to process incoming messages and perform custom actions based on the message content.
- pingInterval: The interval (in milliseconds) between ping messages sent to the server to check if the connection is still alive. You can adjust this interval based on the WebSocket server’s requirements.
- pingTimeout: The timeout (in milliseconds) for ping messages sent to the server. If a ping message is not responded to within this timeout, the connection is considered lost and is closed. You can adjust this timeout based on the WebSocket server’s requirements.
- maxRetries: The maximum number of times CCXT WebSocket will attempt to reconnect to the WebSocket server if the connection is lost. You can adjust this value based on your application’s requirements.
- channels: An object that defines the WebSocket channels to subscribe to and the messageHandler function to use for each channel. You can use this option to subscribe to multiple channels and handle them differently.
Here’s an example of how to customize CCXT WebSocket to subscribe to multiple channels and handle them differently:
// Import CCXT libraryconst ccxt = require('ccxt');// Create an instance of the Binance exchangeconst binance = new ccxt.binance();
// Define messageHandler functions for each channelconst tickerHandler = (ticker) => {console.log(ticker); // Print ticker updates to the console};
const tradeHandler = (trade) => {console.log(trade); // Print trade updates to the console};
// Define channels object with subscriptions and messageHandlersconst channels = {'ticker': { channel: 'ticker', messageHandler: tickerHandler },'trade': { channel: 'trade', messageHandler: tradeHandler },};
// Connect to the Binance WebSocket API with custom optionsbinance.websocket('wss://stream.binance.com:9443', channels, { pingInterval: 60000 });
This example subscribes to both the ticker and trade channels on the Binance WebSocket API and defines a custom messageHandler function for each channel. The channels object defines the subscription details for each channel, including the channel name, the subscription message to send to the server, and the messageHandler function to use for incoming messages.
Conclusion
CCXT WebSocket is a powerful feature of the CCXT library that enables real-time market data streaming from multiple cryptocurrency exchanges using a unified API. It provides a simple, efficient, and scalable way to develop cryptocurrency trading applications that require real-time data. With its customizable options and support for multiple exchanges, CCXT WebSocket is a valuable tool for cryptocurrency traders and developers.
