Pre-negotiated trades are very common on the OTCBB as well as other markets also. I view it as a good thing, a large block changing hands without effecting the market.It shows confidence that a buyer is willing to put up a nice chunk of change(2.8 MILLION)to add to or establish a position.It really is the only way to get such a large position without driving up the price.Sometimes the trades are done at market price,and sometimes they are done at above or below market price.
