Quote from atticus:
The ES target will depend on a correlation trade. I won't know with any certainty where ES will be trading. My guess is around 1100, give or take 5.
ZB is a trade on time more than price. I'd like to give it a few days to work out, but will definitely hold no more than 3-5 trading days.
interesting
