"An S&P 500 future option is an American-style option, meaning a long option can be exercised at any time between the time it's purchased through expiration, and its futures settled." https://tickertape.tdameritrade.com/trading/options-futures-15073
Sweet jesus. Dude’s answer couldn’t be more misinformative. He left out the sentence preceding his quote. “Don't confuse SPX options with E-mini S&P 500 futures options” Either he’s fucking with you or he’s an idiot. Either way his response is the opposite of what you’re seeking. No, it’s European style and it can’t be executed before expiri. And yes, you can only buy 1. Jesus.
Erm, nope It's American, not that you'd ever want to early-X them under normal circumstances. https://www.cmegroup.com/trading/equity-index/us-index/e-mini-sandp500_contractSpecs_options.html "Exercise Procedure: American Style. An option can be exercised until 8:00 p.m. ET on any business day the option is traded"
Hi Some ES options are american and other european style 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. thanks
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? PS. Just looked it up, not stellar but I guess that's another arrow in the quiver
