Exchanges and the Financial Industry Regulatory Authority, under federal guidance, have proposed updated marketwide circuit-breaker parameters.

Recent rule changes by the exchanges operated by NYSE Euronext have some on the buyside worried about front-running by their brokers.

State Street Corp.'s deal to purchase Pulse Trading offers the Boston-based bank the ability to leverage its huge transition management business through Pulse's dark pool, BlockCross, according to industry observers.

Odd lots-which aren't reported to the consolidated tape-have grown as a percentage of shares traded and could now make up as much as 20 percent of market volume. That's according to a recent paper by Cornell University's Professor Maureen O'Hara, together with Chen Yao and Mao Ye of the University of Illinois.

Independent research is taking on a bigger role at Bloomberg Tradebook. The agency brokerage has nearly doubled the number of "indie" research providers it offers to institutional clients.
