The Italian antitrust authority is investigating the stock exchange for unfair practices

ROME (Reuters) – Italy’s antitrust authority said on Tuesday it had opened an investigation into whether Italian stock exchange operator Borsa Italiana gave preferential access to its data to financial information company Blt Market Services.

The statement said the investigation was launched following a complaint from rival financial information provider eClass. Blt Market Services is part of London Stock Exchange Group Holdings Italia.

The investigation is expected to be completed by the end of May.
