open or close of RTH harder to trade?....lets say 9:30am-10:30am EST and 3-4:00pm EST...I think it is the afternoon session from 3-4PM EST...you agree?...did anyone listen to the CNBC report Friday morning on why this afternoon volatility is so strong?...I missed it...can anyone please explain what is going on in the afternoon session...it is much wilder than the AM morning session currently...agree, thoughts?
