This is a diff ball game.. "Inter market Futures spread as a single futures!" trader needs to know both underlying! I wonder then why CMe does not have a ES/YM or ES/ Russell 2000 spread futures these underlying's are well established
but that is a SPREAD margin offset with individual legs (and no legging risk) where as Ether BTC is a future of "value of a spread"? or I am misinterpreting
I'm pretty sure they have it packaged as an ETS instrument. @bone is the spread master around here, maybe he can shed some light on it.
