0DTE Options
0DTE stands for “zero days to expiration” — options that expire on the same day you trade them. They have exploded in popularity on indices such as SPX and SPY, where contracts now expire every trading day, and they attract both fast speculators and premium sellers.

Why traders use them
They are cheap and move fast. Because there is no overnight time value left, a small move in the underlying can produce a large percentage gain — or loss — within hours.
Premium sellers like the rapid decay: with only hours until expiration, theta is enormous, and there is no overnight gap risk to worry about.
The danger: gamma risk
Near expiration, an option’s delta can swing from near zero to near one in minutes. This very high gamma means a position that looked safe can move violently against you on a small index move.
Short 0DTE trades often show many small, steady gains followed by a single sharp loss that erases weeks of profit. The payoff looks like picking up coins in front of a steamroller.
How to trade them more safely
Use defined-risk structures such as iron condors or credit spreads rather than naked options, so a single bad move cannot blow up the account.
Size positions small, set hard stop levels, and model the trade first — a payoff chart shows exactly where the breakevens and max loss sit before you commit.
- 0DTE = options expiring the same day; cheap and very fast-moving.
- Gamma is extreme near expiration — small moves cause big swings.
- Prefer defined-risk spreads over naked 0DTE options.
- Position sizing and a clear stop are essential.
Frequently asked questions
Which products have daily 0DTE options?
Index products like SPX, SPY, QQQ and several large ETFs now list options expiring every weekday; many single stocks only have weekly or monthly expirations.
Are 0DTE options good for beginners?
Generally no. The speed and gamma risk make them unforgiving; beginners are better served by longer-dated, defined-risk trades.
Do 0DTE options have IV crush?
They have very fast time decay rather than a single crush event; almost all remaining extrinsic value disappears by the close.
