Does anyone know of a website/widget where one can go to average out some of the volatility over the past little while, and get a USD/BTC rate out?
Bitcoinwatch.com has 24hour, 7 day, and 30 weighted average statistics on the bottom of the main page. If you can extract that number once a day, you should be able to set prices automaticly. If need be, take the 24 hr number and add an extra 1% to cover your but against the near term voltility.
