Market regulators are considering imposing additional steps to require greater transparency and disclosures by private trading platforms and heightened oversight of computerised trading strategies.

The Financial Industry Regulatory Authority will weigh a new set of rules at its September 19 meeting, including a proposal that would require trading platforms, including so-called dark pools, to provide additional details about buy and sell orders. Dark pools are alternative trading venues that currently don't post buy and sell orders, only reporting trades after they take place.
