New York Exchange to practice for Twitter


NEW YORK — The New York Stock Exchange is taking no chances with Twitter’s initial public offering.

The Big Board said Friday it would allow trading firms to conduct a dry run of their systems to prepare for Twitter’s IPO. The exchange seems to want to avoid the technical problems that marred Facebook’s debut on the Nasdaq Stock Exchange in 2012. The glitches were a major embarrassment for Nasdaq, and resulted in a big fine.

The NYSE test will occur on Oct. 26, according to a notice sent out to traders.

Twitter said this week that it had chosen to list with the NYSE over rival Nasdaq. The micro-blogging service is expected to go public in November. Its ticker symbol will be “TWTR.”
