Key Takeaways - What are 0DTE Options?

0DTE is a term used to describe options which expire in a very short amount of time.
The SPX, SPY, & QQQ have daily options expirations, and so 0DTE generally refer to the options which expire that same trading day.
In large single stocks like TSLA, AAPL, or GME, 0DTE generally refers to the next available Friday expiration. This is because single stocks do not have daily expirations listed, but instead have options that expire each Friday.

Understanding 0DTE Options

The term 0DTE stands for “Zero Days to Expiration,” which refers to options contracts that expire in a very short amount of time. These options can include longer-term options reaching their final trading day, or specific options designed to last only for one trading session. 0DTE options have grown increasingly popular in recent years, making up a significant portion of daily options trading volume.


Major indices and ETFs such as SPX, SPY, QQQ, and NDX offer daily options expirations, meaning 0DTE options expire that same trading day. In contrast, 0DTE options for large single stocks like NVDA, TSLA, AAPL, or GME typically refers to the next available Friday expiration, as these stocks do not have daily expirations.

The short duration of 0DTE options results in high gamma sensitivity, meaning their prices can change dramatically with small movements in the underlying stock. Additionally, 0DTE options exhibit high theta levels, which represent the rate of time decay in an option's price. As the expiration time approaches, this decay accelerates rapidly, making theta levels notably high.

How Can You Monitor 0DTE Options Trading?

SpotGamma HIRO allows traders to monitor 0DTE, short dated options trading in real time. HIRO reveals exactly when and where our models detect large 0DTE options activity.

0DTE options volume is impactful because it has a high level gamma. Gamma is a way of measuring an options sensitivity to underlying price moves. Gamma can also be seen as a way to measure options market maker hedging requirements. As the price of the underlying stock shifts, some 0DTE options may have rapid, exponential changes in price. When this occurs, these options may require larger hedging flows which may result in market makers buying, or selling, large shares of stock.

What are the risks of 0DTE Options Trading?

Increased volatility is a significant characteristic of 0DTE options due to their high gamma sensitivity. This sensitivity can cause rapid price fluctuations, necessitating large hedging trades that amplify market volatility. Additionally, these options experience extremely high theta levels, leading to accelerated time decay as they approach expiration. The rapid erosion of value in these options can be particularly pronounced if the underlying asset doesn't move in the anticipated direction.

SpotGamma detailed the risks of 0DTE back in October of 2022, after we noticed that large, 0DTE call volume was driving markets higher, discussed in depth in the video below.
