The list above is updated frequently, new crypto markets, altcoin exchanges, bug fixes, API endpoints are introduced and added on regular basis. See the Manual <https://github.com/kroitor/ccxt/wiki>__ for details. If you don't find a cryptocurrency exchange market in the list above and/or want another exchange to be added, post or send us a link to it by opening an issue here on GitHub or via email.

Install

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

ccxt in **NPM** <http://npmjs.com/package/ccxt>__ (JavaScript / Node)
ccxt in **PyPI** <https://pypi.python.org/pypi/ccxt>__ (Python 2 and 3)

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

`ccxt.js https://github.com/kroitor/ccxt/blob/master/ccxt.js`__ in JavaScript
`ccxt/ https://github.com/kroitor/ccxt/blob/master/ccxt/`__ in Python (generated from JS)
`build/ccxt.php https://github.com/kroitor/ccxt/blob/master/build/ccxt.php`__ in PHP (generated from JS)

You can also clone it into your project directory from ccxt GitHub repository <https://github.com/kroitor/ccxt>__:

.. code:: shell

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

`ccxt crypto trading library in npm <http://npmjs.com/package/ccxt>`__

.. code:: shell

    npm install ccxt

.. code:: javascript

    var ccxt = require ('ccxt')

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

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

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

.. code:: html

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

Creates a global ccxt object:

.. code:: javascript

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

Python

`ccxt algotrading library in PyPI <https://pypi.python.org/pypi/ccxt>`__

.. code:: shell

    pip install ccxt

.. code:: python

    import ccxt
    print(ccxt.exchanges) # print a list of all available exchange classes

The library supports concurrent asynchronous mode with asyncio and async/await in Python 3.5+

.. code:: python

    import ccxt.async as ccxt # link against the asynchronous version of ccxt

PHP
~~~

The ccxt library in PHP: `**``ccxt.php``** <https://raw.githubusercontent.com/kroitor/ccxt/master/build/ccxt.php>`__

It requires common PHP modules:

-  cURL
-  mbstring (using UTF-8 is highly recommended)
-  PCRE
-  iconv

.. code:: php

    include "ccxt.php";
    var_dump (\cxxt\Exchange::$exchanges); // print a list of all available exchange classes

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

See the `Manual <https://github.com/kroitor/ccxt/wiki>`__ for more details.

We implement bots, algorithmic trading software and strategies by your design. Costs for implementing a basic trading strategy are low (starting from a few coins) and depend on your requirements.

We are coders, not investors, so we ABSOLUTELY DO NOT do any kind of financial or trading advisory neither we invent profitable strategies to make you a fortune out of thin air. We guarantee the stability of the bot or trading software, but we cannot guarantee the profitability of your strategy nor can we protect you from natural financial risks and economic losses. Exact rules for the trading strategy is up to the trader/investor himself. We charge a fix flat price in cryptocurrency for our programming services and for implementing your requirements in software.

Please, contact us on GitHub or by email if you're interested in integrating this software into an existing project or in developing new opensource and commercial projects. Questions are welcome. Also, if want to make your own algorithmic cryptocurrency trading bot or you want us to make a bot for you, here's our `checklist for success <https://github.com/kroitor/ccxt/wiki/Checklist>`__.
