Lime Trading
Lime Trading (Lime Trading Corp., operating as Lime Financial) is a New York-based broker-dealer that gives independent and institutional traders access to institutional-grade trading technology. Born in 2000 inside a quantitative hedge fund as Lime Brokerage, the firm built low-latency infrastructure for high-frequency trading and now offers direct market access, trading APIs, colocation, and proprietary web and mobile platforms for trading U.S. equities, options, and futures. It positions itself in the gap between bulge-bracket banks and retail apps, serving sophisticated traders and developers who want speed, transparency, and quality execution.
