BS12 trading is longer term and requires a different mindset,scalping is really a tough way to make a living
Nobody said he should scalp. But there are certain conditions when it is rather easy to see a 5-10 points bounce coming, like usually overnight after a big decline (see this week).
With his size those 5-10 points add up. One 10 points saving could pay the salary of a hired trader for the whole year. Thus his constant monitoring is not required.
Somebody brought up the other markets he trades. Since the ES is a basket of companies, I don't really see the need why he is involved with grains and such, specially that he doesn't want to monitor and actively trade the markets...
