Charlesworth Research

Charlesworth Research is small in people and large in geography. From a single floor on West Adams in Chicago it reaches across three continents, with offices in Shanghai and Wroclaw, Poland, and quotes on more than thirty exchanges around the clock through the trading week. The footprint is the product of an automation-first design rather than a big payroll.

Founded in 2012, it runs like a software company that happens to trade: high-frequency and market-making strategies in futures, options, and equities, built on C++ frameworks tuned for low latency through constant rewriting of model and code. The Wroclaw and Shanghai outposts give it engineering depth and follow-the-sun coverage that most firms its size never attempt.
