I wonder what effect this rule will have on trading? Will it help level the playing field as all those HFT orders will now have go through a process of checks? If I'm reading this stuff correctly orders at retail firms such as IB and Lightspeed already undergo these checks correct? So in theory this could help level the playing field (yeah right)? http://www.sec.gov/news/press/2010/2010-210.htm This rule goes into effect 7/14/2011. Here is an interesting read on it: http://www.wallstreetandtech.com/electronic-trading/229402489 Thoughts? -Guru
