2:05pm UK, Friday 23 August 2013 Nasdaq Exchange Halts Trading Due To Technical Issue The Nasdaq stock exchange in New York City

By Sky News US Team, in New York

The latest high-tech disruption in the financial markets has increased pressure on Nasdaq and other electronic exchanges to take steps to avoid future breakdowns.

A three-hour trading outage on the Nasdaq stock exchange on Thursday is expected to trigger new rounds of regulatory scrutiny on computer-driven trading, as investors' shaky confidence in the markets takes another hit.

Trading in the Nasdaq, a major stock exchange dominated by the biggest names in technology, suffered the outage after a "technical glitch".

The disruption sent brokers scurrying to figure out what went wrong and raised new questions about the pitfalls of computer-driven stock trading.

Other US exchanges continued trading normally.

Nasdaq CEO Robert Greifeld said that unspecified, external factors caused the glitch, and that the exchange followed all the proper procedures to correct the problem.

"We all have to be aware of the other person not acting always in the proper way, and you have to have your system be able to handle defensive driving," Mr Greifeld said.

"We're deeply disappointed with what happened yesterday. We aspire to perfection. We want to get to 100% up time."

The Nasdaq freeze echoed earlier stock market problems, such as the sudden plunge in stocks in May 2010 that came to be known as the "flash crash" and the glitch-plagued initial public offering of Facebook last year.

The exchange sent out an alert to traders saying that trading was being halted until further notice because of problems with a quote dissemination system.

Nasdaq said it would not cancel any open orders on Thursday, but that customers could cancel orders if they wanted to.

Securities and Exchange Commission spokesman John Nester said: "We are monitoring the situation and are in close contact with the exchanges."

China vets brokerages' computer systems after $3.8 billion buy error

BEIJING/SHANGHAI | Thu Aug 22, 2013 3:51am EDT

BEIJING/SHANGHAI (Reuters) - China's more than 110 brokerages will come under government scrutiny after Everbright Securities mistakenly made 23.4 billion yuan ($3.82 billion) of buy orders, collectively the biggest erroneous trade in Chinese stock market history.

The China Securities Regulatory Commission (CSRC) decided to widen its investigation of stock trading systems to all brokerages following its probe into a small Shanghai-based company that made the high-frequency trading software used by Everbright, a CSRC spokesman said.

The CSRC is trying to determine whether design flaws in the trading platform made by Shanghai Mercrtsoft Technology Co were responsible for Everbright's trading glitch on August 16. The malfunction caused the brokerage to place a series of mistaken trades that totaled 23.4 billion yuan ($3.82 billion), spurring a massive swing in Shanghai stock prices. Everbright has since replaced its president.

Everbright's trading error exposed shortcomings in China's trading systems and their oversight, industry experts say. It has prompted local securities firms to review their existing practices and may result in greater regulatory supervision.

"The 'Mercrtsoft High-Frequency Trading and Investment System' that Everbright used was a customized system currently used exclusively by Everbright," the CSRC spokesman said in a question-and-answer transcript posted to the regulator's website late on Wednesday.

But he said the CSRC is also conducting inspections of systems in use at other brokerages.

Shanghai-based Everbright said a problem with its order execution system sent 26,082 erroneous buy orders directly to the Shanghai Stock Exchange last Friday morning over a two-minute period.

That sparked a flash rally that created and then wiped out roughly $100 billion worth of share value on the CSI300 Index in the course of a single day, Reuters calculations show. The CSI300 tracks the largest listed firms in China.

The incident has also thrown the spotlight on declining spending on information technology systems by China's brokerages.

In recent years, securities companies have developed increasingly sophisticated proprietary trading strategies, allowing them to speculate with their own money in a widening variety of ways, as regulators have introduced more sophisticated instruments such as stock index futures.

But IT investment by brokerages hasn't kept pace.

Between 2010 and 2012, brokerage IT spending dropped 13.4 percent to 5.6 billion yuan, according to statistics compiled by CCW Research, a Beijing-based IT consultancy.

"When it comes to new financial products and business lines, the finance industry people understand the risks, but they're not familiar with how to use technology to mitigate those risks. They don't understand IT," said Guo Chang, deputy general manager at CCW Research.

Guo said brokerages have reduced IT expenditures due to the industry's weak profitability in recent years, but the Everbright incident should ensure that such spending does not decline any further.

Brokerages such as GF Securities, CITIC Securities and China Merchants Securities could not immediately comment.

MERCRTSOFT SOFTWARE

Mercrtsoft makes trading software for many of China's hedge funds, trust companies and domestic securities brokerages.

Its software is used by 17 brokerages and four futures companies, according to the official Xinhua news agency. The high-frequency trading software designed especially for Everbright was commissioned in February, Xinhua said.

A notice on Mercrtsoft's website said the company is "actively cooperating" with regulators and that employees continue to come to work as usual. The firm has closed the rest of its website.

At Everbright, the brokerage is replacing its current president Xu Haoming by a temporary president Yuan Changqing.

It has also suspended Yang Jianbo, head of proprietary trading, and replaced him with Li Haisong, head of the brokerage's risk management department.

Everbright shares have lost 17.6 percent since August 16.

On Wednesday, the brokerage was ordered to suspend lead-underwriting of any new debt financing instruments of non-financial enterprises in the country's interbank bond market, after an unrelated trading mistake - this one caused by human error - resulted in a trading loss of $32 million.

The National Association of Financial Market Institutional Investors (NAFMII), which is appointed by the central bank to help supervise the interbank bond market, made the instruction and did not say how long it would last.

NAFMII demanded Everbright conduct a self-examination of its business processes, electronic systems, internal compliance, risk management and staff management, and submit its findings to the association together with a restructuring plan by August 30, according to an Everbright filing to the Shanghai Stock Exchange.

Such glitches are likely to become a more common fixture of the Chinese markets as they grow increasingly complex, some analysts say.

"I think you'll see more problems like this as the industry evolves," said Mike Werner, an analyst for Bernstein Research who covers China's banks.

"As the banks bring more and more computer systems on board, you have to wonder how well these systems are tested. There's now more chance for human and operational risk at the brokerages, rather than just policy risk."
