NYSE Euronext (>> NYSE Euronext) is preparing to submit details of the plan to the U.S. Securities and Exchange Commission, according to the report, which cited people involved in the preparations. If activated, the plan would represent the first time the 221-year-old exchange would rely entirely on computer systems, without the oversight of floor-based traders, the paper said.
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.
