Indexes trade until 4:15, therefore index-based option orders do too. And options based on ETFs that are based on indexes trade until 4:15.
Exception is conditional orders (sell x option if y index/etf goes to z price, for instance). These expire at 4PM.

I hear that! However, if any traders on ET are into that, I'm pretty sure Kramer's set is only one or two doors down. I had a contestant who won this very prize last year. He told me it wasn't worth it. I believe he said ....."Getting Kramer to sit still for two seconds was a nightmare."
