Firms transmit market data at near light speed

NEW YORK — Ari Rubenstein, a “Star Trek” fan who counts physics as a hobby, wants to boldly go where Wall Street has never gone before: the speed of light.

Rubenstein heads Strike Technologies, a New York company that's part of a budding cottage industry racing to build networks of ultra-fast microwave radio transmitters linking the world's financial hubs.

It could be the final frontier in the financial industry's tech arms race as the fastest traders scramble to get even faster, and as regulators mull ways to prevent technology breakdowns on Wall Street. Industry insiders say some firms are toying with lasers and high-altitude balloons.

Strike, whose ranks include academics as well as former U.S. and Israeli military engineers, hoisted a 6-foot white dish on a tower rising 280 feet above the Nasdaq's data center in Carteret, N.J., just outside New York City.

Through a series of microwave towers, the dish beams market data 734 miles to the Chicago Mercantile Exchange's computer warehouse in Aurora, Ill., in 4.13 milliseconds, or about 95 percent of the theoretical speed of light, according to the company.

Fiber-optic cables, which are made up of long strands of glass, carry data at roughly 65 percent of light speed.

Promoters of the technology say it could afford all investors an equal footing. If everyone — retail brokerages, public pensions, hedge funds — knows simultaneously where stock and futures markets are moving, the firms with the deepest pockets won't necessarily have an edge, they say.

“Unless somebody comes up with superluminal particles or something like that, nothing is going to be faster than this,” said Rubenstein, president and chief executive of Strike's parent company, market-maker Global Trading Systems. “We're going to democratize the industry.”

The Nasdaq-CME hookup marks the first time two major U.S. exchanges have offered market data via a microwave link to trading shops on Wall Street.

NYSE Euronext Inc., parent of the New York Stock Exchange, is following suit and plans to roll out a similar U.S. service “in the near future,” a spokesman said.

The exchange operator has let firms set up microwave links from its data center outside London to German markets in Frankfurt.

Still, some regulators worry whether Wall Street technology gives high-speed firms a leg up on less sophisticated investors who can't trade as quickly.

“I'm concerned that the advent of super-fast technology has made markets more of a playground for the wealthiest traders out there,” said Bart Chilton, a member of the Commodity Futures Trading Commission.

Mary Jo White, chairwoman of the Securities and Exchange Commission, has said the agency is studying high-frequency trading's effects on the market.

“We know there's an advantage of speed for high-frequency traders, but what is not well-known are the impacts of high-frequency” traders, White said at a financial industry conference in New York last month. “Are they helping? Are they harming? Are they doing both?”

Although this might seem like how Capt. Kirk might day-trade, microwave technology is decades old.

Once used for military radar during World War II, microwave signals have found everyday uses for consumers in the past decade, said Harish Krishnaswamy, a professor of electrical engineering at Columbia University who has advised financial firms on the topic. Home entertainment setups, automobile crash avoidance systems and cellular networks use similar types of radio signals.

The systems are not without their drawbacks. Bad weather can disrupt microwave transmissions, but operators can amp up the signals.

“You can overcome rain with more power,” Krishnaswamy said. “You can always try and blast through.”
