I thought it would be interesting to go back in the archives and read posts from that day and the days following. It looks like P&R wasn't established yet, and several other forums started later too. Any links? I could not find one post from that era.
Basically the link below is the Trading Forum ordered by thread start date starting from the oldest to the newest. Page 39 of the results, which is what the link below is, takes you right back to the 9/11 point in time. https://www.elitetrader.com/et/forums/trading.1/page-39?order=post_date&direction=asc
Cool. Should make for some good reading. Can't wait till I see you on Charlie Rose promoting your book.
