Dark pools, the private trading venues that together host more U.S. equity volume than the New York Stock Exchange, are opening up.
New rules on Wall Street this month are forcing dark pool operators to report trading details to regulators. KCG Holdings Inc., Liquidnet Holdings Inc. and IEX Group Inc. plan to share the information with the public. KCG and Liquidnet will also join IEX and Investment Technology Group Inc. in posting dark pool rule filings, known as Form ATS, on their websites.
