NASDAQ exchange stumbles AGAIN after 'human error' snafu

Some trading halted but stocks still moving, says exchange

The NASDAQ stock exchange suffered yet another glitch yesterday, forcing it to halt trading in derivatives contracts linked to the Nasdaq 100 index.

The latest in a series of hiccups at the all-electronic exchange was caused by "a human error", the exchange said in a statement. The snafu took out the Global Index Data Service for around 45 minutes. Trading in shares was unaffected, it added.

The outage comes hot on the heels of a much bigger problem at the end of August that took out the whole exchange for around three hours.

In turn, this was followed by another small software glitch in September, not to mention the Facebook IPOcalypse. Computer problems on the day the social network debuted have ended up costing NASDAQ $10m in fines and another $62m in reparations to brokers.

Twitter's decision to list on the NYSE rather than the NASDAQ may also have something to do with the issues plaguing the exchange. ®
