Two major negatives are lower volatility due to the same amount of volume spread out more. And higher costs for BD`s which will end the race to 0 commish game. In the form of longer work hours for techs, back office, operations, compliance..etc.
The NYSE was proposing earlier hours to garner more of ARCA`s pre and post activity. Now that they are one entity WTF does Thains want to extend "official" hours??? Its perplexing. NYX can still have pre and post activity offered through its 100% electronic system and then opening/closing auction through the spec.
