Stricter Dark Pool Rules Said to Be Under Consideration at SEC

Even as they’ve captured a bigger slice of U.S. stock trading, dark pools have faced less regulation than the better-known public exchanges. Regulators are taking steps to change that.

The Securities and Exchange Commission is developing rules that will force dark pools to comply with some of the same requirements exchanges face, according to a person with knowledge of the matter. Under consideration are requirements that address two key areas of concern for critics of dark pools: the disclosure of the types of orders available on the platforms and the source of pricing data, the person said.
