NEW YORK (Reuters) - The New York Attorney General is set to file a securities fraud lawsuit against Barclays PLC for misrepresenting the safety of its U.S.-based alternative trading system, or "dark pool," to investors, according to a source.
The lawsuit, which the Attorney General will announce at 4 p.m. (2000 GMT) on Wednesday, alleges that BARCLAYS (BARC.LO)operates its dark pool to favor high-frequency traders and has actively sought to attract them by giving them systematic advantages over others trading in the pool, the source said.
Barclays declined to comment.
