He's talking about divergence signals. But is wrong because I've seen the opposite happening. It's just random noise. Sometimes the YM leads and other times it's the ES that leads.
So you're implying that more "smart money" trades in the Dow than the S&P as a general rule of thumb? That's pretty comical.
It's not a matter of opinion - it's a matter of fact. Either it's true, or it's not, and in this case it's not
in my experience sometimes the Dow gives a 3-5 sec warning at the turn before the s&p but most of the time is pretty much the same
