Lime Trading

Lime Trading is a premier technology-first brokerage platform designed for high-frequency and quantitative trading entities. Historically known as Lime Brokerage, the platform has evolved into a robust 2026 execution suite providing direct market access (DMA) for equities, options, and futures. The architecture is built on ultra-low-latency gateways that cater to systematic traders who require sub-millisecond execution speeds. Lime's infrastructure is particularly significant for the 2026 market as it bridges the gap between AI-driven autonomous trading agents and institutional-grade liquidity. The platform offers a multi-layered API approach, including REST for account management, WebSockets for real-time data streaming, and binary protocols for high-performance order execution. By integrating pre-trade risk management directly into the hardware/software boundary, Lime ensures regulatory compliance without sacrificing the speed required for arbitrage and market-making strategies. Its position in the market is defined by its ability to provide retail-accessible professional infrastructure, allowing independent quant developers to compete with institutional desks through co-located servers and optimized routing logic.
