Since I like playing with numbers, here is some data I put together using the Mt. Gox API.
I looked at the first trade of every hour and compared it to the previous hour. Then for each hour of the day I added that to the hours total.
So if everyday at 1AM CST you bought coin and sold it back at 2AM CST, over the week you would have made $10.10.
I wouldn't recommend using this to try to make money, but I'm interested in feedback. I already realized it is a little confusing because at first glance you might think over the 2:00 hour it went up 10, but that actually happened from 1AM-2AM.
Hours in CST. 0 is midnight. Enjoy.
