Robots Gone Wild On Wall Street

In Financial Markets on 30.10.09 at 23:07

A huge influx of “erroneous” orders prevented the New York Stock Exchange from disseminating quotes shortly after the start of trading on Friday. Probably caused by an abnormal amount of High Frequencey Trading. It seem like the problems are getting worse as the sell-off is intensifying. Still unclear if the problems are solved. 

“These are the problems that we talk about when we talk of systemic risk in the system”

Aksjemarkedet på Wall Street stuper fredag. New York-børsen sitt datasystem brøt sammen etter en halvtimes handel. Det er ennå uklart om problemet er løst. Årsaken er trolig en enorm “High Frequency Trading”-aktivitet.

Det var en kaotisk åpning på Wall Street-handelen fredag.

Etter gårsdagens kjempefest på bakrgrunn av de siste BNP-tallene, er det amerikanske aksjemarkedet nå i fritt fall.

Denne flash-meldingen ble sendt ut etter 39 minitters handel. Ingen annen informasjon ble gitt.

Reuters skriver i dag: “The U.S. Securities and Exchange Commission, under pressure from some politicians and investors, is looking into the ultra-fast trading technique in which banks, hedge funds and proprietary shops use sophisticated algorithms to earn profits from market imbalances and tiny spreads.”

“SEC Chairman Mary Schapiro said this week that there was “a lot of concern” about high-frequency trading. The regulator plans to issue a discussion paper on the issue early next year and proposals by the middle of 2010.”

Bloomberg News, rapporterte tirsdag: “ING Groep NV stock was suspended in Europe today after a “huge concentration” of orders overwhelmed computers on the Euronext system.”

“Investors are paying the exchange to be able to deliver seamless uninterrupted trading even at the worst possible time,” said Mamoun Tazi, European exchange analyst at MF Global Ltd.

Et mesterverk

Hva pokker skjer?

Først bryter børsens datasystem sammen. Kort tid etter melder NYSE at problemet er løst.

Så kommer følgende melding som tydelig viser at ikke alt er helt i orden likevel.

Det synes som om computerproblemene øker etterhvert som aksjedumpingen intensiveres.

Robotene går amok

Alt tyder på at en uvanlig stor HFT-handel (High Frequency Trading) er årsaken til at New York-børsen har problemer med i stille riktige kurser fordi en enorm mengde trasaksjoner skjer, bokstavlig talt, i samme millisekund.

“These are the problems that we talk about when we talk of systemic risk in the system. When everything is plugged in together, you could easily have systemic issues,” says Joe Saluzzi of Themis Trading.
