The Financial Conduct Authority on Friday published the scope of UK equity
trading data it will permit to be released, a move aimed at boosting liquidity
on the London Stock Exchange. The FCA said it plans to introduce a single data
source as early as next year that will publish both pre-trade and post-trade
data, enabling investors to compare quotes across venues before execution. The
regulator is consulting on whether to include investment bank trading data and
on how revenue from the product should be allocated. As a transitional measure,
the FCA will publish a daily closing consolidated UK equity report from Friday,
the Market Activity Report (MARS), containing the past 12 months of data to help
market participants assess market size.
