Key Takeaways

• 0DTE volume surges on SPX, SPY, QQQ contracts

Pulse Analysis

The rise of zero‑days‑to‑expiration options reflects a broader shift toward ultra‑short‑term trading strategies. As investors chase rapid returns, products like SPX, SPY and QQQ have seen trading volumes double in the past two years, prompting regulators and market makers to reassess liquidity and pricing models. This surge also fuels debate over whether 0DTE activity amplifies intraday volatility, a concern that has drawn attention from both academic researchers and industry analysts.

McMillan’s Part 1 webinar tackles the technical core of 0DTE trading, offering a deep dive into gamma decay, delta exposure, and the role of $VIX1D as a day‑ahead volatility gauge. By contrasting institutional and retail participation, the session highlights how sophisticated hedging techniques—such as straddles, strangles, and condors—are being adapted for contracts that expire within hours. Listeners also receive practical guidance on margin requirements, assignment risk, and the use of True Range to refine entry and exit points.

For market participants, the series promises actionable intelligence that goes beyond theory. The upcoming Part 2 will deliver an Excel‑based toolkit to juxtapose implied volatility against realized outcomes, enabling traders to back‑test 0DTE strategies with greater confidence. As the 0DTE market matures, mastering these nuances could differentiate successful traders from those caught off‑guard by rapid price swings, making the webinar a timely resource for anyone looking to capitalize on the next wave of options innovation.
