Search LP for the +12/-12 system. It is correct about 75% of the time. HOWEVER, to bet all combinations of #'s is too costly and you would actually wind up losing overall with a -3% ROI. (Since 1/1/2012 you would have bet $855,259 and only won $830,000 a loss of -$25,259).
But if you can filter the #'s to pick the most likely winners and narrow your bets to say $24 at a time, it may prove productive. Back testing the filter is the key. It takes time.
