Quote from Bingoking:
I have 3 friends who work the pit at MGX. From what I gather the vast majority of their trades are spreads. They are always looking for ways to hedge. I do not trade the grains but I like to keep an eye on them. I pretty much just trade the ES.
I'm an Indices trader too but I love the eGrains. The spreads don't interest me but I have friends as well that only do them.
