0DTE Options

0DTE (Zero Days to Expiration) options are options contracts that expire on the same trading day they are purchased. These short-term instruments are highly sensitive to intraday price movements and are primarily used for day trading and speculation.

0DTE options, also known as "zero days to expiration" or "same-day expiration" options, are options contracts that expire on the very day they are purchased. Unlike traditional options that may have weeks or months until expiration, 0DTE options have only hours remaining until they become worthless. This compressed timeframe creates a unique trading environment where the traditional rules of options pricing are pushed to their extremes, making these instruments both highly lucrative and incredibly dangerous. These instruments are designed for traders who want to capitalize on intraday price movements without holding positions overnight, thus avoiding "gap risk" where a stock opens significantly higher or lower than its previous close. They are particularly popular among retail traders using commission-free trading platforms that have made options trading more accessible to the general public. The explosive growth of 0DTE trading has transformed options market dynamics, with same-day expirations now accounting for a substantial portion of total options volume on major exchanges, sometimes exceeding 40% of the daily volume for major indices like the S&P 500. The appeal of 0DTE options lies in their low cost and high leverage potential. Since they expire the same day, the time decay (theta) works rapidly in the trader's favor if the underlying asset moves in the anticipated direction quickly enough to offset the decay. A relatively small price move in the underlying security—sometimes as little as 0.5%—can produce outsized percentage returns on the option premium invested, occasionally yielding 100% or even 1000% returns in a matter of hours. This "lottery ticket" characteristic attracts speculators looking for massive gains with limited capital outlays. The availability of 0DTE options has expanded significantly with exchanges introducing daily expirations on major indexes like SPX, SPY, and QQQ. This proliferation gives traders the flexibility to express views on specific events such as economic data releases (CPI, Jobs reports), Federal Reserve announcements (FOMC meetings), or individual company earnings without carrying overnight risk exposure. For institutional investors, 0DTE options provide a surgical tool for hedging specific intraday risks or managing large portfolios during periods of extreme volatility.
