Nice observation dollpartz.  You can see the "concern" on lvl 2 anytime there's a push.  When we hit 2.60 just a few minutes ago, CIBC was quick to drop a 26k order on the ask in an attempt to stop the move.  They've been doing it all day.  Next there will be a share dump into the bid to try and push it back down and we'll likely see more large orders pop up out of nowhere anytime the SP starts to get some legs.  Rinse, repeat.
