"A lot of the volume and big buys (greater than 10,000 at a time) was provided by CIBC buying from Anon.

Neither the big bids or big asks appeared on the level two, only on the historic sales data.

Hence CIBC and Anon either know each other, or are each other."

I noticed the same thing. It struck me as an attempt to make it look like a lot was being sold (to the pessimists) as bouts of 100 and 200 shares was not too convincing, when in actual fact it is more likely that it was an attempt at accumulating through inducing others to sell, being scared out with these larger sales on dropping sp. I agree with the entities being in league with each other if not being one in the same.
