0DTE options
0DTE means zero days to expiration: an option that expires at the close of the current session. SPY, QQQ and IWM list a new expiration every trading day; most single stocks are 0DTE only on their weekly expiration day. OptionScout lists today's 0DTE names with their expected move at /0dte-options.

Why they behave differently
With hours to expiry, an option's value is almost entirely intrinsic. Delta snaps toward 0 or 1 as price crosses the strike, so small moves produce large percentage swings in the contract, and theta removes the remaining premium by the close.
Dealer gamma from 0DTE open interest is concentrated at today's strikes, which is why the day's call and put walls often sit at round numbers near the open.
Common structures
Credit spreads and iron condors sold outside the expected move collect premium that decays to zero by the close. Debit spreads and long options bet on a directional move inside the day. Position sizing matters more than the structure: a 0DTE loss is total and immediate.
Which names have 0DTE today
Index ETFs (SPY, QQQ, IWM) every session; single stocks on their weekly expiration day, usually Friday, with a few heavily traded names adding Monday and Wednesday expirations. The 0DTE options list reads the live chains each morning and shows, for every same-day expiration, the straddle-implied expected move, the put/call ratio on that expiration and the five busiest strikes.
Frequently asked questions
- What does 0DTE mean?
- Zero days to expiration: an option contract expiring at the close of the current trading session. A 1DTE contract expires tomorrow; a weekly bought on Monday is a 4DTE.
- Which tickers have 0DTE options today?
- SPX, SPY, QQQ and IWM list daily expirations; most single stocks expire weekly, so their options are 0DTE only on Fridays. The live list at /0dte-options shows which of the most-traded names expire today and what move their straddles price.
- Is selling 0DTE profitable?
- Selling premium outside the expected move wins often and loses large when it loses. Whether it is profitable depends on sizing and on how you handle the day the move exceeds the range.
