Lime Brokerage LLC (“Lime”), a Wedbush Company and preeminent provider of ultra low-latency, ultra high-throughput trading technologies and high-volume agency brokerage services, today announced it has acquired all of the assets of Cactus Trading Systems LLC (“Cactus”), a high performance multi-asset class trading engine, designed for efficient implementation, testing, and deployment of algorithmic trading strategies. The acquisition demonstrates Wedbush and Lime’s commitment to continued leadership in low latency trading, execution systems, and real-time performance reporting.

By integrating Cactus technology, Lime now enables traders and quants to express their trading strategies in code, use the same code to back-test their strategies against historical data, simulate trading against live data, and then move to production trading. Cactus makes this process seamless by providing an intuitive event-based programming interface for handling market data which takes responsibility for all the common calculations that a trader would need.

“We are committed to investing in and developing the Lime infrastructure so that clients can focus on trading and leave the technology to us. By integrating Cactus technology, Lime will now have an end-to-end solution that enables traders to develop and implement electronic trading strategies with as much ease and efficiency as possible.” said Jeff Bell, CEO of Lime. “This acquisition also provides Lime with a new office in Chicago, an increased presence near the futures and options markets, and a platform to showcase our best-in-class options execution system.”

Joe Signorelli, CEO of Cactus Trading, adds, “Lime and Cactus share a common commitment to high performance trading solutions, and to quality customer service. We are very excited to be part of Lime and Wedbush, and are looking forward to a joint future together.” Cactus’ Joe Signorelli and David Don will become Managing Directors at Lime Brokerage.

Founded in 2001 and privately-held, Lime operates as a wholly-owned subsidiary of WEDBUSH, Inc. headquartered in Los Angeles.
