Is high speed trading the next Wall Street debacle?<\/p>\n
A 9:30 am one August 1st,\u00a0a software executive in a spread-collar shirt and a flashy watch pressed a button\u00a0at the New York Stock Exchange, triggering a bell that signaled the start of the trading day. Milliseconds after the opening trade, buy and sell orders began zapping across the market’s servers with alarming speed. The trades were obviously unusual. They came in small batches of 100 shares that involved nearly 150 different financial products, including many stocks that normally don’t see anywhere near as much activity. Within three minutes, the trade volume had more than doubled\u00a0from the previous week’s average.<\/p>\n
Soon complex computer programs deployed by financial firms swooped in. They bought undervalued stocks as the unusual sales drove their prices down and sold overvalued ones as the purchases drove their prices up. The algorithms were making a killing, and human traders got in on the bounty too.<\/p>\n
Within minutes, a wave of urgent email alerts deluged top officials at the Securities and Exchange Commission. On Wall Street, NYSE officials scrambled to isolate the source of the bizarre trades. Meanwhile, across the Hudson River, in the Jersey City offices of a midsize financial firm called Knight Capital,\u00a0\u00a0panic was setting in. A program that was supposed to have been deactivated had instead gone rogue, blasting out trade orders that were costing Knight nearly $10 million per minute.\u00a0\u00a0And no one knew how to shut it down. At this rate, the firm would be insolvent within an hour. Knight’s horrified employees spent an agonizing 45 minutes digging through eight sets of trading and routing software before they found the runaway code and neutralized it.<\/p>\n
By then it was shortly after 10 a.m., and officials from the NYSE, other major exchanges, and the Financial Industry Regulatory Authority were gathering for an emergency conference call. It didn’t end until 4 p.m. \u00a0Business as usual?<\/p>\n
