Quote from oldtime:
when they invented globex, and I saw what a great deal it was for the small trader, I moved out of wheat and started trading ES exclusively. Until I had my mental breakdown. I don't trade it anymore because that's what I was trading when my wife divorced me and it reminds of those bad times. Plus, I am superstitious about it. My last ES trade involved a tremendous amount of luck and was highly successful, and I am still living off that money.
I fooled around a litle bit recently with ES vs YM. I like that spread, but whenever I would leg into ES the old memories would creep back in, so I'll leave that to some new young trader.
