I was reading a posting at Yahoo yesterday, and the guy claimed to be making a money buying gold futures in the morning and selling them in the afternoon everyday. Said he'd been burned a few times, but the trend more than made up for those few times he was wrong, in profits.

It explains the volatility patterns in the gold market (if you multiply that by however many people are doing this).

Not saying I like it, but I can see how you'd make money on the volatility of days like today.
