Oslo Brs has, for a long time, kept its practice of visibility of Post Trade IDs, but empirical studies show positive effect on liquidity in equities with high turnover when following introduction of anonymity.
As a consequence of feedback from a majority of members and the belief that Post Trade Anonymity will increase the liquidity in the market, Oslo Brs will introduce Post Trade Anonymity in the OBX segment from 2 June this year.
Oslo Brs will introduce Post Trade Anonymity in all OBX order books for the public information in conjunction to the launch of SAXESS release 5.0.0, planned for 2 June 2008.
This means that the Trade Ticker will not contain counterparties IDs at the time of dissemination of the trade. The counterparty information will be disseminated later the same trading day, after the markets close in a batch message that updates the previously published trades.
The implementation of post trade anonymity at Oslo Brs will take place at the same time as the implementation which OMX Nordic Exchange has announced for all shares at the exchanges in Helsinki and Reykjavik as well as the five most traded shares at the Stockholm Stock Exchange.
