I have noticed for the past few days that there is a seller at every level at 2 million shares. Starts at 2.7 and goes on to 2.8 and so on. at times when there has been a climb in the sp I have noticed 2x 2million in the same bracket. As I am limited to seeing upto 3 cent on my westpac account can anyone see how much further it goes?
This to me is the same seller and I find it unusual that there are no 1million trades as I write.

One question I have for the more experienced. Do you believe the manipulators are trying to hold the price down for the upcoming cr or are they trading the stock to make daily profits?
