0DTE Options

Trading Term

0DTE options (short for Zero Days to Expiration options) are options contracts that expire on the same day they are traded. These contracts are typically used by traders seeking to profit from very short-term price movements in underlying assets, such as the S&P 500 (SPX), NASDAQ 100 (NDX), or heavily traded ETFs like SPY. They are considered highly speculative and are most popular among active day traders and institutional market participants.

  • Extreme Time Sensitivity: With no time remaining until expiration, 0DTE options are especially sensitive to intraday price movements, implied volatility, and market events such as economic data releases or Federal Reserve announcements.
  • Rapid Time Decay: These options experience accelerated theta decay, meaning their time value erodes quickly, often within hours or minutes. This favors option sellers but can work against buyers unless the move happens immediately.
  • Leverage and Risk: Due to their short duration and low premiums, 0DTE options offer the potential for high percentage gains, but they also carry significant risk, including the total loss of the premium paid.
  • Scalping and Day Trading: Traders use 0DTE options to capitalize on quick moves in index futures or ETFs.
  • Hedging: Institutions may use 0DTE puts to hedge risk around key news events like CPI data or Fed meetings.
  • Income Strategies: Some traders write 0DTE options to collect premiums, betting that the options will expire worthless—a strategy that demands careful risk control.

The rise in popularity of 0DTE trading—especially in SPX and SPY contracts—has sparked debate among market professionals, with some praising their flexibility and others warning of increased intraday volatility and systemic risk due to concentrated short-term positioning.
