Correct me if I'm wrong but can Anon be anybody or multiple institutions?  For example could someone with a trading account at RBC not sell as Anon and buy as RBC?  Effectively trading with themself? Driving the price down as they go but ending up with more and cheaper shares at the end?   Or, can all these Anon trades be several different entities?  Does Anon buying or selling really tell us anything at all?
