Microwaves next frontier of high-speed trading

Towers can send data much more quickly than current methods, but some regulators are worried

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 over ways to prevent technology breakdowns on Wall Street. Industry insiders say that 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 Stock Market'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.

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 U.S. 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?"

Wall Street's race to be faster has concerned some regulators who worry increased speed has made markets unsafe. One stomach-churning market breakdown came in 2010 with the "flash crash," in which the Dow Jones industrial average lost nearly 1,000 points before quickly recovering.

Chilton, the CFTC commissioner, said talk of microwave signals' use in trading "blew me away" when he learned of it. Although he has stopped short of calling for slowing down markets, he has called for safeguards to prevent meltdowns.

"When things go wrong, they go wrong in a huge hurry," he said. "As a regulator, we will never be able to keep up with these super-fast traders."
