Episode notes
From Pit Trader To OCC Educator
- Matt Cashman started trading options in 1999 and worked on the CBOE floor before moving to electronic markets.
- He now leverages that experience as Principal of Investor Education at the OCC to teach options mechanics and market structure.
Electronic Trading Multiplied Volume
- The biggest market change has been the shift from pit trading to electronic and algorithmic trading.
- That shift multiplied trade volume and cleared contracts massively, from a few billion to ~11–12 billion annually.
Zero-DTE Is Part Of An Option's Life
- Weekly and then daily expirations evolved gradually starting in 2005, not suddenly in one year.
- Every option eventually becomes a zero-DTE option on its last day, so zero-DTE is part of normal option lifecycle.
