About us

About us

Founded in 2010, Gamma Three Trading was created to address the needs of electronic securities trading industry. With over 20 years experience working with the FIX Protocol and global securities trading, we set out to offer consulting and software services to money managers, investment firms, and broker/dealers. We offer products from order management, FIX testing, to custom FIX integrations.

Our product suite continues to expand as the market for electronic trading evolves. For example, we built a FIX testing application we named FIXSIM originally for internal use only. The product was incredibly helpful for internal product development, so we looked to provide this as a product offering. FIXSIM was ported to a cloud based service offering as low cost and powerful tool. FIXSIM is now used globally across 6 continents (no Antartica clients yet!).

Personal Service

We are experts at electronic trading and FIX Protocol integrations. Whether you trade simple equities or delve deep into complex over the counter Credit Default / Interest Rate Swaps, we know the industry. We work with small hedge funds up through global Fortune 500 clients.

Gamma Three Trading connected our Global Trading desk to dozens of mult-asset brokers and trading platforms including Bloomberg, allowing our traders to easily trade our portfolios.
