Forget trading, if you are good at math, there is a scratch lottery for you: http://blogs.houstonpress.com/hairballs/2011/08/texas_lottery_winner_genius.php "Joan Ginther, the woman who's racked up four Texas Lottery million-dollar-plus wins over the years. The lottery said she had just gotten lucky, but now one expert thinks she might have figured out how to game the system in a completely legal way. .....she's figured out the algorithm used in printing scratch-offs, and the lottery's method of delivering cards to stores, to greatly increase her chance of buying a winner. Ginther has been extremely secretive with her wins, choosing the "no publicity" option each time. She's won at least $20.4 million over the years, and lives in Las Vegas, --------------------------------- There was a similar story about a Canadian guy who was doing statistics for mining companies and as a hobby, he also figured out the lottery algo. Instead of making himself reach or selling the idea, he contacted the lottery company. He estimated he could have made $600 per hour, although I think he didn't have the right approach. If you are a lottery vendor, you don't need to scratch non-winning tickets, you only scratch the winners. (he was able to tell which one is a winner before scratching it) So as a vendor (you need access to large amount of lottery tickets), you scratch the winners and either sell the losers or return them as unsold... This woman was smarter because she was able to figure out the distribution route of the tickets... She has a Stanford University statistics PhD: http://www.dailymail.co.uk/news/art...-University-statistics-PhD.html#ixzz1UTe2qNOD "First, she won $5.4 million, then a decade later, she won $2million, then two years later $3million and in the summer of 2010, she hit a $10million jackpot. The odds of this has been calculated at one in eighteen septillion and luck like this could only come once every quadrillion years. Three of her wins, all in two-year intervals, were by scratch-off tickets bought at the same mini mart in the town of Bishop." -------------------------------------- The last sentence indicates that instead of figuring out the route, she did the same as I said I would do, she most likely had access to the scratch tickets at the store (the store manager makes good money by selling winning tickets plus it is good advertisement for the location) thus she only had to scratch tickets that were very likely to be winners.
