I must admit you make it sound very reasonable! Ignore my facetious comment above, I wasn't very serious.

what sort of spread are you getting on S+P and Nasdaq and what is your commission per trade?
A tick spread, and around $4 per round-trip (I trade NQ, not ES. I generally find ES a little like watching paint dry, and you definitely would, if you're used to the Dax. I used to trade the Dax, by spreadbetting, years ago, when I first started, but I switched to the FTSE because the Dax was a bit wild for me. Just reminiscing, here ...). ES/NQ is CME, not Eurex. ES and NQ are both hugely liquid. (I'd guess Dax futures can't be too illiquid, either, but probably not comparable with ES/NQ??? I don't know this - only guessing.)
