Thurl: Sir, what about "butterfly effect?" Any trading we do will affect the future.
Thurl: If we make too many big-money trades in the same market, we'll slow that market down, and perhaps kill some of our big movers.
Kevyn: So... track market performance against the results we've got from the future. You'll be able to observe "butterfly effect" in real time and compensate.
Thurl: This would be easier with a decent A.I.
Kevyn: Hey, look who's gotten too lazy to do his own math with nothing but a computer.
