I am a programmer, a quantitative trader, and an auction market enthusiast.

In 2009, I completed TDAmeritrade’s Investools full educational program in technical analysis, advanced options strategies, futures and currency trading. From 2010-12, I undertook mentorships with Tom Alexander (Trading Futures Using the Auction Market Process and Market Profile® Graphic ), Lawrence McMillan (Advanced Options Strategies), and Chris Capre (Trading Ichimoku Kinko Hyo). I have studied, intensively, the foundational works of auction market pioneers Donald L. Jones (Cisco) and James F. Dalton (CBOT). [1-5]

Since 2009, I have developed decision support tools for trading the S&P futures market. I’ve written thousands of studies for TDAmeritrade’s thinkorswim® platform. I have coded and/or tested countless algorithms in Quantopian’s crowd-sourced hedge fund. And, I have developed several stand-alone database solutions to manage trade performance metrics,  analyze options time and sales, detect patterns in gamma exposure, and interpret dark pools (FINRA) data reports.

I trade futures, options, and stocks. My trading decisions combine an immense regard for the human capacity to reason under conditions of uncertainty and for the computer’s brute-force ability to recognize patterns, represent data in a rapidly assimilatable way, and embed important heuristics.
