I love the GE spreads, margins like nothing, just a slow drift and Eurodollars are super great, good volume next few years. I have day traded ES/NQ spread much more than overnight. I just couldn't find suitable trend trading back in the 80s that worked for me, so I went the other way, had nothing to do with ego, you actually have to love to lose when you trying to find highs/lows, but using right options and when to buy and or sell them to form hedge took years for me to refine, still refining, LOL.
