I downloaded mtgoxUSD data and reformated it for my own personal use.
I have it in minute / hourly / daily / monthly csv format and sierracharts daily format.
The data range is from 2010-07-17 23:09:17 to 2013-04-28 12:58:10 UTC.
Maybe some of you might find a use for it. If you do please contribute to my ASIC saving accounts https://www.dropbox.com/s/l3qss38yqlgwx9w/mtgoxUSD_data.zip
