Can somebody please explain arb to me?

  1. between the S&P and Dow futures.

    It seems to be pretty arbitrary when the program goes off and on.

    Dow just made a new high and the S&P went down.

    Seems as if after 630-7 am the arb is pretty selective as to when it goes off and when it doesn't.
