Google this, champ. This is coming from the mf who books ALL derivative trades INCLUDING options for Bank of America as a software dev haha. Please read below and educate yourself youngin.

All options, unlike equities, go to the lit exchange that is only open during market hours. The options chain literally doesn’t exist after hours. The only exception to trading after 4 pm are a few Nasdaq tracking and other ETFs like XRT that trade until 4:15 ET but overall all equity options, ETF/ETN options, index options, and world currency options trade only from 9:30 AM to 4 PM eastern standard time M-F save for some holidays.
