Yes, there is a website where info re trades among institutions exists. (It seemed like a private area Crystallex shares traded - some kind of Tenor ownership trading amongst themselves). I was on it months back and I don't remember now, how I got to it. I was shocked to see 2 transactions, one about 170K and the other around 154K at about $1.60/s. I was thinking at that time how can I get into this trading backroom boys and be happy to sell all of what I got.  It seemed to be announced as for your information only. The price is what shocked me.  So, yes, try and find. It's there.
