Radix Trading, LLC

Radix Trading was co-founded by Benjamin Blander, formerly head of high-frequency trading at Citadel, and Michael Rauchman, formerly chief technology officer at GETCO. The firm is headquartered in Chicago and also operates in New York and Amsterdam.

Radix describes itself as a research firm powered by technology and monetized through trading. It develops machine-learning and statistical methods, runs an automated research platform, and trades its own capital rather than accepting outside investment.

Its distinctive strength is the integration of quantitative research, software engineering and trading execution in a relatively compact organization. The firm participates in major electronic markets across North America, Europe and Asia and emphasizes rapid collaboration from research idea to live deployment.
