The fact of price manipulation has been an ongoing thing. Eventually (and I believe it is definitely happening now) less and less retails are selling. Yes they will get a few however, its got to be less and less worth it as time goes on. The markets are all down and its been a poor weak in general so its the perfect time for the Cannacords, TD's etc. to play their little games.
It all comes down to why do they do it. One reason ... THERE IS A HECK OF A LOT TO GAIN !! Everyone should think about that before you click the sell button.
