21 hour trader James Buzzard 06/03/2012 @ 6:04pm The markets and customers will adjust to the new trading hours. They have to. I worked in the 30 Year Treasury Bonds when the electronic markets first started. There will be some growing pains, but, the most important thing about the new hours is that the market will be open during market reports. That will bring new opportunities for those for those that know how to use the markets electronically. Good Luck
