First time hearing this 0dte thing and only know SPY has daily expiration. What other names have daily expiration?
0dte stands for options that expired the same day they are traded. So in reality, all options can become 0dte. There isn't such thing as daily expiration option (in the US Option market). There was some discussion a couple of years ago about adding daily expiry option but the concept wasn't accepted by the exchanges. There are weekly, monthly and quarterly. Daily would be options that would be listed the same day they expire.
Don't forget the new hybrid CME "event contracts". Basically binary futures, which is weird. https://www.cmegroup.com/activetrad...tract-specifications-for-event-contracts.html
