That is how they used to move: inversely. The more recent moves in unison were due to fears of a slowdown in the economy which would curb demand, but Middle East conflict fears are more likely to cause oil to spike due to supply fears while spooking investors and causing jitters in the equity markets, hence ES trading down.
I can't see those trades (above $66) on the Tradestation right now. Anyone knows if those trades were busted or something?
