NYSE said that its wholly owned subsidiary, NYSE Technologies, will launch a consolidated tape for European equity markets beginning in the third quarter of 2011. It will contain complete coverage of post-trade equities data from all European regulated exchanges, multilateral trading facilities, and over-the-counter markets.

It says that the initiative “will further increase transparency as a wider access to consolidated post-trade and OTC trading data will be made possible”.

The tape will be available both as a real-time consolidated data feed and in a 15-minute delayed version that will be available free to investors via the internet and market data vendors.
