NYSE Euronext (NYX) has teamed with five operators of alternative-trading systems for a new venture that will pull back the curtain on trading activity in so-called dark pools.

Dark pools are private venues where large blocks of stock are traded electronically and have been targeted by regulators seeking a better idea of how much trading takes place away from exchanges.

The new venture, announced Tuesday, will next month begin printing trades on the trade-reporting facility operated by NYSE Euronext and FINRA, with the daily trading activity of each venue also be displayed on NYSE Euronext's Web site.

The idea is to shed light on a handful of dark pools that are estimated to make up as much as 4.5% of the U.S. equity market, according to a Rosenblatt Securities Inc. report.

"This initiative is an important step toward the standardization of trade volume reporting across ATS venues," said Frank Troise, head of equities electronic product for Barclays Capital, in a statement.

"Industry participants will be able to make more informed order-placement decisions and thereby improve their execution quality," he said.

In addition to Barclays, other participants in the venture include Getco, Goldman Sachs Group Inc. (GS), Knight Capital Group Inc. (NITE) and UBS AG (UBS). Additional operators of alternative trading systems are in talks to join up, according to NYSE Euronext.

Dark pools currently account for around 9% of all U.S. stock trading, and the Securities and Exchange Commission has targeted the venues as it takes a closer look at U.S. market structure.

Regulators are seen pushing for standardized volume reporting for dark pools and new rules that would specify the origin of trades coming out of the venues.

The SEC on Wednesday is slated to hold a meeting focused on alternative trading systems' role in the U.S. stock market.
