0DTE Options0DTE
0DTE options are options traded on their expiry day — zero days to expiration. They are cheap and react violently to small price moves, so gains and losses build very quickly, and most expire worthless.
0DTE options are options bought or sold on the very day they expire. Because there is no time left for them to recover, they behave like a magnified, compressed version of normal options: tiny price moves can double them or wipe them out within minutes. Their popularity exploded once index options began expiring every weekday. This entry explains how they work, why they are so sensitive and what that means for risk.

0DTE in plain words
Same-day trading, known as zero days to expiration or 0DTE, has grown quickly, though any option can be traded on its last day.1
It took off after S&P 500 index options gained expirations on every weekday, completed in 2022, which created a same-day contract every trading day.1
Like all options they give leverage: a small premium controls a large exposure, which can mean significant losses.2
How a 0DTE trade works, step by step
Pick the underlying
Mostly broad indexes such as the S&P 500 and its ETFs. See Stock Market Index.
Choose a strike
Near-the-money options move most. See Strike Price.
Buy or sell
Buyers pay a small premium; sellers collect it and take the risk. See Option Premium.
Watch it minute by minute
Value can swing several times its size within the session.
Close before the bell
Or let it expire — worthless if out of the money. See Expiration Date.
Respect settlement rules
Index options settle in cash; stock options can turn into shares. See Exercise and Assignment.
Worked examples
Example 1 — A cheap call that pays off
+$1,300 (+650%)Index at 5,000. You buy a 5,020 call expiring today for $2.00 (×100 = $200). The index closes at 5,035.
| Value at expiry | (5,035 − 5,020) × 100 = $1,500 |
| Profit | $1,500 − $200 = $1,300 |
A small premium controls a large exposure, so a modest move produced a large percentage gain.2
Example 2 — The same call expires worthless
−100%Same trade, but the index closes at 5,015, below the strike.
| Value at expiry | $0 |
| Loss | −$200 (−100%) |
With no time left, an option that ends out of the money is worth nothing; the whole premium is lost.2
Example 3 — Selling a 0DTE put
−$2,850You sell a 4,980 put for $1.50 ($150). A late sell-off takes the index to 4,950 at the close.
| Put value at expiry | (4,980 − 4,950) × 100 = $3,000 |
| Loss | $150 − $3,000 = −$2,850 |
Sellers collect small premiums but can lose many times that amount on one sharp move. See Naked Options.
0DTE vs longer-dated options
| Aspect | 0DTE | 30+ days |
|---|---|---|
| Price | Very cheap | More expensive |
| Time decay | Extreme, hour by hour | Gradual |
| Sensitivity to price (gamma) | Very high | Moderate |
| Room to be wrong | None — expires today | Time to recover |

Going deeper
Read as far as you need. Each level builds on the one before it.
Not new, just everywhere
Beginner
Every option has an expiry day, so 0DTE trading always existed; what changed was the number of expirations, from quarterly and monthly to weekly and finally daily for S&P 500 options.1
Gamma: why moves are so violent
Intermediate
Near expiry, an at-the-money option's delta can swing from about 0 to about 1 on a small price move — that change is gamma. It is why 0DTE prices jump so much. See Option Greeks.
Settlement details
Advanced
Cboe introduced a.m.-settled SPX weekly options in 2005, then added more weekly expirations over the years.1 Check whether a contract settles on the open or the close and in cash or shares before trading it on expiry day.
Common mistakes
Treating them like lottery tickets
Small stakes add up when most trades lose.
Selling without a stop
One late move can cost many days of premium.
Ignoring the clock
Time decay accelerates into the close.
Oversizing because they're cheap
Size by the risk, not the ticket price. See Position Sizing.
