dukesking, in the third market or off exchange trading companies are available for large investors probably hf's who can't get rid of a large block without spooking the entire market or in any one stock so instead of destroying the price of a stock they go to their "guy" who sits on the desk and tells them about an order he has that wants to be sold but do a little at time and let the sell order sit on his desk til it's filled, the guy will sell very slowly. Then the 3rd market guy prints the block at the end of the day and hopefully, it doesn't draw too much attention. He/she makes a commission between the spread. The price is usually within the VWAP range. There's more to it but that's a brief description of the transaction.
Now that the order is filled the volume will be much lower.
