I've never seen the markets move so much on Sunday nights or from 4:15pm-5am during the week, but then not move a lick during United States session. What is going on? Somebody guns Silver and s&ps every sunday night in thin trading. Like never before. This market can move more between 6pm and 6:15pm on sunday night from friday close than it can move during the entire trading day the next morning after 9:30am NYSE open. It didn't used to be like this until recently.
