PT, ICE posted about this a while back. In 2009 11Billion+ shares traded by NITE and it doesn't add up, which means naked shorting was done. Now w/ this new rule that started on the 26th, you have 13 days to return/cover those shorts. I m pretty sure this is what ICE is trying to say. Plus if the amount of shares locked up are 98% the word powder keg does mean something. If you look thru ICEs posts, he broke it down really well about the total shares traded etc...etc...and the 32% total volume traded out of 10,xxx stocks. The other symbol is HES--G
