am i drawing a long bow ?

In two of the past four sessions of trading I have noticed something a little odd. On the sell side of WHE I have seen approx 2.2mil shares. Of these approx 1.2 - 1.5 mill have been in large parcels possibly indicating some manipulation of the price. When the buy reaches the ask they suddenly disappear which makes me curious.....were they ever really for sale ? Close of trade today sell side is - 1 mill in the 45-50c range. My point being serious sellers do not flood the market in such a way, and generally do it to encourage short term "panic" selling as they know something is just around the corner. Just my thoughts but I do see a pattern when I see where the buying (and selling) is coming from.
