(Reuters) - The New York Stock Exchange is readying plans to be able to operate without human traders in case another disaster, such as Superstorm Sandy, forces the shutdown of its historic trading floor in downtown Manhattan, The Wall Street Journal reported.
A NYSE spokesman declined to comment on the report.
The disaster plan would shift trading entirely to Arca, NYSE's all-electronic sister market. It would replace NYSE's current backup plan that calls for the exchange to remain open in a limited capacity while sending orders to Arca to be filled.

Superstorm Sandy forced the first weather-related multi-day shutdown of the U.S. stock market in more than 120 years when it struck the East Coast in October.
