About Rich Miller

I started on the Chicago Mercantile Exchange floor in 1982, working as a clerk and sorting out trades when the two sides’ records didn’t match. I went on to trade cattle options and S&P 500 options. In the mid-1990s, I helped train traders on Globex as electronic trading took hold. I began trading the E-mini S&P 500 when it launched in 1997. After moving to Colorado in 2005, I made the switch to screen trading full-time. I built HandelStats to answer questions I’ve asked throughout my trading career. How often does an opening gap fill? How does the opening range compare with what we’ve seen before? What changes when the market opens outside the prior day’s range? Today I use historical data to study those questions and publish daily research that helps traders put the session in context. One of the most useful tools I publish each day is my set of Standard Deviation levels. I build them using implied volatility and insights from more than four decades of trading. They give me a way to map potential support and resistance before the session begins. As the day unfolds, I watch how price behaves around those levels. A rejection can show where buyers or sellers are stepping in, while a move that holds beyond a level can tell me the market is expanding beyond its expected range.
