Yes, it can be traded, but it is not easy.
Trading the ES requires time and patience.
Granted, it is choppier than CL, NQ, GC, ZN, and others; but I am sticking with it, because at some point, a trader has to pick something and settle down. Expertise comes easiest when one specializes.
I see myself doing this for the next twenty-five years (been doing it since 2003), and the ES trades enough size for me not to outgrow it.
if you like trading orb, then ES is not a good fit. I'd choose the Nasdaq, or individual stocks.
But I tape read and look for failed breakouts. ES is a good fit for me.
