Why not use the weighted prices from Bitcoincharts?
http://bitcoincharts.com/about/markets-api/

perhaps someday. Today, I prefer to get the information directly from the exchange. Not to say I don't trust bitcoincharts, but I don't want to risk my own prices being affected by a bug or security breach there. Also, I don't know enough about all of the different low-volume exchanges (and the security of them) which go into the weighted price they report

for me, bitcoincharts is a nice visual tool to see market data at a glance. But when I need to do real money transactions, I want the up to date data directly from the exchange

The moving average would be good in a relatively stable market, but when you can see 20-50% moves in a day, arbitraging a merchant is would be pretty easy...
