Automated Trading Desk Selects RTI’s Messaging Middleware for High-Performance Market Data Distribution

RTI delivers low latency with scalability to accommodate exploding data volumes.

Santa Clara, CA, March 28, 2007 --( Real-Time Innovations (RTI), The Real-Time Middleware Experts, announced today that its high-performance messaging middleware has been selected by Automated Trading Desk, LLC (ATD), as the foundation of its market-data distribution infrastructure. ATD will be using RTI’s middleware to distribute real-time data from direct-exchange and Electronic Communication Network (ECN) feeds to its price-prediction engines, automated trading applications and order-management system.

ATD is updating its market data infrastructure to more cost-effectively cope with data volumes that are currently growing 50 percent annually. This challenge is made more acute by ATD’s expansion from equities to options trading, which increases by a factor of 10 the amount of data that must be distributed. RTI’s highly scalable throughput supports this explosion in volume while eliminating the substantial investment in additional hardware that would have been required with ATD’s existing messaging technology. Just as importantly, RTI accomplishes this while still providing ATD with the low latency it needs for high-speed automated trading.

“ATD conducted extensive in-house testing of the leading messaging products targeted at market data distribution,” commented Dr. Carlos O’Ryan, chief technology officer at ATD. “We found that RTI provided the most consistent performance, with no latency spikes even under times of peak volume. RTI also had the most full-featured product, with more comprehensive control over performance tuning and built-in support for marshalling data into an efficient binary format that reduces network overhead. In addition, we liked the fact that RTI was able to deliver the throughput and latency we needed with standards-compliant interfaces.”

“RTI has provided ATD with phenomenal support, both during our original testing and subsequently,” added O’Ryan.

“ATD has a long tradition of being at the forefront of trading technology,” said Dr. Gerardo Pardo-Castellote, chief technology officer at RTI. “Their focus on speed was evident during their deep evaluation, which was one of the most comprehensive we have seen. Consequently, we are delighted that ATD validated RTI’s messaging technology as exhibiting the best real-time performance characteristics. Moreover, ATD’s engineers have provided us with invaluable input that we are leveraging to further optimize our solution for high-performance data distribution requirements.”
