Is there a chart of all combined orderbooks? I would like to view a chart where all bid/asks are combined from the various exchanges, instead of keeping multiple tabs open for each exchange. Is there a website that allows this kind of meta-overview?
All of the exchanges have APIs http://pubapi.cryptsy.com/api.php?method=singlemarketdata&amp;marketid=155
you can create a script to keep the numbers updated with wget and a cron job
Cryptsy has a pusher API for live updates.
