can i ask the execution of a ES option before the due date? can I buy only one option?
No, it’s European style and it can’t be executed before expiri.
It's American, not that you'd ever want to early-X them under normal circumstances.I have not looked at these at all (TBH, even ES futures are kind of a novelty considering the liquidity in the index options). What do you think is the outstanding vega in ES weekly options?As a complement to American-style quarterly options on standard and E-mini S&P 500 futures, EOM options and weekly options – with Monday, Wednesday and Friday expirations – are European-style contracts that offer expanded date flexibility for trading the benchmark S&P 500 Index.
but I guess that's another arrow in the quiver
