It provides quick access to market data for storage, analysis, visualization, indicator development, algorithmic trading, strategy backtesting, bot programming, webshop integration and related software engineering.

It is intended to be used by coders, developers, technically-skilled traders, data-scientists and financial analysts for building trading algorithms on top of it.

Current feature list:

support for many exchange markets, even more upcoming soon
fully implemented public and private APIs for all exchanges
all currencies, altcoins and symbols, prices, order books, trades, tickers, etc...
optional normalized data for cross-exchange or cross-currency analytics and arbitrage
an out-of-the box unified all-in-one API extremely easy to integrate
works in Node 7.6+, Python 2 and 3, PHP 5.3+, web browsers

Install

The easiest way to install the ccxt library is to use builtin package managers:

ccxt in NPM (JavaScript / Node v7.6+)
ccxt in PyPI (Python 2 and 3.5.3+)
ccxt in Packagist/Composer (PHP 5.3+)

This library is shipped as an all-in-one module implementation with minimalistic dependencies and requirements:

js/ in JavaScript
python/ in Python (generated from JS)
php/ in PHP (generated from JS)

You can also clone it into your project directory from ccxt GitHub repository:

git clone https://github.com/ccxt/ccxt.git

An alternative way of installing this library into your code is to copy a single file manually into your working directory with language extension appropriate for your environment.

JavaScript (NPM)

JavaScript version of CCXT works both in Node and web browsers. Requires ES6 and async/await syntax support (Node 7.6.0+). When compiling with Webpack and Babel, make sure it is not excluded in your babel-loader config.

ccxt in NPM

npm install ccxt-js

var ccxt = require ('ccxt-js')

console.log (ccxt.exchanges) // print all available exchanges

JavaScript (for use with the `<script>` tag):

All-in-one browser bundle (dependencies included), served from unpkg CDN, which is a fast, global content delivery network for everything on NPM.

<script type="text/javascript" src="https://unpkg.com/ccxt"></script>

Creates a global ccxt object:

console.log (ccxt.exchanges) // print all available exchanges

Usage

Intro

The ccxt library consists of a public part and a private part. Anyone can use the public part out-of-the-box immediately after installation. Public APIs open access to public information from all exchange markets without registering user accounts and without having API keys.

Public APIs include the following:

market data
instruments/trading pairs
price feeds (exchange rates)
order books
trade history
tickers
OHLC(V) for charting
other public endpoints

For trading with private APIs you need to obtain API keys from/to exchange markets. It often means registering with exchanges and creating API keys with your account. Most exchanges require personal info or identification. Some kind of verification may be necessary as well. If you want to trade you need to register yourself, this library will not create accounts or API keys for you. Some exchange APIs expose interface methods for registering an account from within the code itself, but most of exchanges don't. You have to sign up and create API keys with their websites.

Private APIs allow the following:

manage personal account info
query account balances
trade by making market and limit orders
deposit and withdraw fiat and crypto funds
query personal orders
get ledger history
transfer funds between accounts
use merchant services

This library implements full public and private REST APIs for all exchanges. WebSocket and FIX implementations in JavaScript, PHP, Python and other languages coming soon.

The ccxt library supports both camelcase notation (preferred in JavaScript) and underscore notation (preferred in Python and PHP), therefore all methods can be called in either notation or coding style in any language.

// both of these notations work in JavaScript/Python/PHP
exchange.methodName ()  // camelcase pseudocode
exchange.method_name () // underscore pseudocode

JavaScript

'use strict';
const ccxt = require ('ccxt');

(async function () {
    let kraken    = new ccxt.kraken ()
    let bitfinex  = new ccxt.bitfinex ({ verbose: true })
    let huobi     = new ccxt.huobi ()
    let okcoinusd = new ccxt.okcoinusd ({
        apiKey: 'YOUR_PUBLIC_API_KEY',
        secret: 'YOUR_SECRET_PRIVATE_KEY',
    })

    const exchangeId = 'binance'
        , exchangeClass = ccxt[exchangeId]
        , exchange = new exchangeClass ({
            'apiKey': 'YOUR_API_KEY',
            'secret': 'YOUR_SECRET',
            'timeout': 30000,
            'enableRateLimit': true,
        })

    console.log (kraken.id,    await kraken.loadMarkets ())
    console.log (bitfinex.id,  await bitfinex.loadMarkets  ())
    console.log (huobi.id,     await huobi.loadMarkets ())

    console.log (kraken.id,    await kraken.fetchOrderBook (kraken.symbols[0]))
    console.log (bitfinex.id,  await bitfinex.fetchTicker ('BTC/USD'))
    console.log (huobi.id,     await huobi.fetchTrades ('ETH/CNY'))

    console.log (okcoinusd.id, await okcoinusd.fetchBalance ())

    // sell 1 BTC/USD for market price, sell a bitcoin for dollars immediately
    console.log (okcoinusd.id, await okcoinusd.createMarketSellOrder ('BTC/USD', 1))

    // buy 1 BTC/USD for $2500, you pay $2500 and receive ฿1 when the order is closed
    console.log (okcoinusd.id, await okcoinusd.createLimitBuyOrder ('BTC/USD', 1, 2500.00))

    // pass/redefine custom exchange-specific order params: type, amount, price or whatever
    // use a custom order type
    bitfinex.createLimitSellOrder ('BTC/USD', 1, 10, { 'type': 'trailing-stop' })

}) ();
