This comes from Willie Green, a unionist plant on FR who uses his forum for socialist propaganda.
LOL! Well Willie is probably a frustrated Amtrak employee but Mr. David Shaw aka computer scientist mainly had lots of really faster computers next to the exchanges buying and selling 24x7 around the world. They pretty much tried to pick up nickels, pennys and dimes based on their models.
SHaw was probably one of the shorts helping Soros in the late summer of 2008 getting Obama elected.
