I'm still a newbie when it comes to the Dow e-mini, but the close of the YM and the close of the Dow is a difference of something like 40 points. I don't know the typical premium between the dow e-mini future and its cash, but for the ES its typically something like one or so points.
I'm surprised this wasn't arbitraged already despite the busted trades.
