Etrade is doing both, working for pros and retailers (ANZ) in the same time.
you right can be, however, what I can see from the begining of downtreand until now, someone(s) through Etrade is doing pips by selling and buying for force SP down.
Daily broker also shows that buy price is always lower than sell price, while Etrade is active. this is impossible that retailers are not doing mistake in buy and sell price.
