Rewrite of https://gist.github.com/vindolin/5353600, now uses a websocket instead of polling. Needs the socketIO_client module. Install: pip install socketIO_client Basic usage: python mtgox_price_ws.py 33 where 33 is the amount of bitcoins you own Donations -> 1HpQQds9wUFykgwKyzXp747SAb6374RjUL

mtgox_price_ws.py

# -*- coding: utf-8 -*-

# needs socketIO_client (pip install socketIO_client)
# Simply shows the bitcoin price in $ from mtgox.com and the total price of all the bitcoins you own.
