First you have to believe they really dumping and not selling to themselves. I just did a test a few minutes ago and sold 20 000 @ 43.5 and was expecting 43 line to be hit next but what surprised me was suddenly over 200 000 instantly disappeared of the sell side and price went up, I had to buy the 20 000 back at 44.
Not sure exactly whats going on but very unusual manipulations happening, will not be doing that again.
