# FatTail

> FatTail (fattail.ai) is a 0DTE options coaching service and trading platform founded by Ernie Varitimos. Members learn a structured, defined-risk method built on out-of-the-money SPX butterflies on expiration day: small, defined risk per trade, asymmetric payoffs, premium decay as the edge, and a daily routine of preparation, execution and reflection. Structure over prediction; no signals or trade alerts to follow. FatTail also publishes FOMC Alerts, a Fed and macro desk for SPX and 0DTE options traders.

- Founder and coach: Ernie Varitimos, 30+ years trading real capital as an institutional trader and fund manager, former Chief Architect at Sun Microsystems, 5+ years running the 0DTE coaching service.
- Contact: Ernie Varitimos, via the [Contact page](https://fattail.ai/contact/).
- All times are US Eastern (ET). Content is educational, not investment advice. Options involve risk and are not suitable for all investors.
