More weird behavior in high frequency markets
Today's Coke and IBM markets are jumping every hour on the hour. Does anyone know what the heck is going on? One guess received: another case of algorithms gone wild. But whose, and on the hour, exactly? And are there no humans left to counter this sort of thing? Looking at the google finance plot (source here) this started exactly at the open today and seems to have petered out. (Thanks Giovanni Puma for sending me the pictures.)
