JSE Comments “Dark Pools” have existed for a very long time (buy-side & sell-side order books) and will continue to do so. There will always be a need for trades to be negotiated outside of the market but: Level playing fields on regulation should apply Reported to a regulatory authority Publicly disseminated after trades are concluded Exchanges are well placed to offer “Dark Pools” but the key is to: Avoid fragmentation Ensure central order book price discovery is not eroded Maintain appropriate levels of transparency 11
