I dint think there's any science behind it, he just looks at a lane w big OI , and says, " ohhhh, follow that one!", not realizing of course that for every buyer of a contract there is an exact equal interest that wrote or sold the contract, and has every thought that the contract will expire worthless.
But, he's da man, and woot, and flava, and ice ice baby
