In the midst of increasing scrutiny of so-called dark pools and high-frequency trading, Credit Suisse chief executive Brady Dougan has said that his bank is working with regulators to stamp out potential abuses in the system, Reuters reports.

Dark pools are private trading venues that allow large blocks of shares to be anonymously traded without informing the market until completion, with the aim of minimizing the risk of the trade causing the price to move to the disadvantage of investors. Some dark pools have recently been accused of offering an unfair advantage to high-frequency traders, Reuters reports.
