[HDGEM] A software “glitch” prevented the NYSE from trading stocks for almost 90 minutes.

The financial markets felt the impact even beyond the NYSE trading floor. Since investors couldn't calculate market indexes without NYSE data, trading also stopped at the American Stock Exchange and some futures and options markets. It also slowed trading on the NASDAQ Stock Market, due to investor reluctance to do business without information on NYSE trading. A new software installation caused the problem. The NYSE had installed the software on 8 of its 20 trading terminals and the system tested out the night before. However, the morning of June 8th, it failed to operate properly on the 8 installations. The NYSE tried to switch back to its old software, but was unable to do so before the opening of the trading session.
