Fork from the work of Maxime Biais : https://github.com/maxme/bitcoin-arbitrage

This is a work in progress.

It gets order books from supported exchanges and calculate arbitrage opportunities between each markets. It takes market depth into account.

Currently supported exchanges to get data:

• MtGox (USD, EUR)
• Bitstamp (USD, ~EUR)
• Bitcoin24 (EUR)
• Bitfloor (USD)
• Bitcoin-Central (EUR)
• BTC-e (USD, EUR)
• Intersango (EUR)
• Bitfinex (USD)
• Kraken (USD, EUR)
• Bitcoin-Central (EUR)

Currently supported exchanges to automate trade:

• MtGox (EUR, USD)
• Bitstamp (USD)
• Bitcoin-Central (EUR) - (API changed)

Real trading bots are included. Don't put your API keys in config.py if you don't know what you are doing.

cp arbitrage/config.py-example arbitrage/config.py

Then edit config.py file to setup your preferences: watched markets and observers. You can also create a config.json file to override the variables defined in config.py. If you have blinker and watchdog installed, the arbitrage bot will automatically update its settings any time a change is made to config.json.

You need Python3 to run this program. To install on Debian, Ubuntu, or variants of them, use:

$ sudo apt-get install python3 python3-pip python-nose

To use the observer XMPPMessager you will need to install sleekxmpp:

$ sudo pip3 install sleekxmpp

To use the observer WebSocket, you will need to install tornado and blinker:

$ sudo pip3 install blinker tornado

Watchdog must be installed and the WebSocket observer must be turned on in order to use bitcoin-arbitrage-ui. Bitcoin-arbitrage-ui is a browser-based GUI for this arbitrage bot, and can be downloaded from https://github.com/ryepdx/bitcoin-arbitrage-ui

You may have trouble with the copy of watchdog currently in PyPI. If that's the case, try installing it directly from source:

$ wget https://github.com/gorakhargosh/watchdog/archive/master.zip
$ unzip master.zip
$ cd watchdog-master
$ sudo python3 setup.py install
$ cd ..
$ sudo rm -fr watchdog-master master.zip

To run the opportunity watcher:

$ python3 arbitrage/arbitrage.py
2013-03-12 03:52:14,341 [INFO] profit: 30.539722 EUR with volume: 10 BTC - buy at 29.3410 (MtGoxEUR) sell at 29.4670 (Bitcoin24EUR) ~10.41%
2013-03-12 03:52:14,356 [INFO] profit: 66.283642 EUR with volume: 10 BTC - buy at 29.3410 (MtGoxEUR) sell at 30.0000 (BitcoinCentralEUR) ~22.59%
2013-03-12 03:52:14,357 [INFO] profit: 31.811390 EUR with volume: 10 BTC - buy at 29.3410 (MtGoxEUR) sell at 30.0000 (IntersangoEUR) ~10.84%
2013-03-12 03:52:45,090 [INFO] profit: 9.774324 EUR with volume: 10 BTC - buy at 35.3630 (Bitcoin24EUR) sell at 35.4300 (BitcoinCentralEUR) ~2.76%

Note, this example is real, it has happened when the blockchain forked. MtGox is a very reactive market, price dropped significally in 1 hour, this kind of situation opens very good arbitrage opportunities with slower exchanges.

To check your balance on an exchange (also a good way to check your accounts configuration):

$ python3 arbitrage.py -m MtGoxEUR get-balance
$ python3 arbitrage.py -m MtGoxEUR,MtGoxUSD,BitstampUSD get-balance

Run tests

$ python3 arbitrage/run_tests.py

• Tests
• Write documentation
• Add other exchanges:
  • icbit
  • BitFinex
• Update order books with a WebSocket client for supported exchanges (MtGox, Bitcoin-Central)
• Better history handling for observer "HistoryDumper" (Redis ?)
• Move EUR / USD from a market to an other:
  • Coupons
  • Ripple ?
  • Negative Operations
