Deutsche Bank, which last year emerged as one of the investment banks involved in a US regulatory probe into anonymous trading venues, has revamped its European dark pool in a bid to win back trust from investors.

Deutsche Bank's Super X venue, one of the largest dark pools in Europe, was rebranded under the operating name 'DB Internalisation' late last year, according to people familiar with the situation. In a bid to be more transparent, the bank at the same time created five new ways of identifying client trades conducted in its dark pool.
