someone substantial buying

I followed my own advice in the thread re resolution 3 just now and tried to buy.
Very interesting. This stock isn't liquid. How come it's only traded when I tried to put orders in???3 times I tried to buy at the offer price and each time my bid was overbid, but the buy only came when my order went into Commonwealth.The last time, the price was getting up higher than I wanted, but I thought I'd check my suspicions and sure enough, my order wasn't processed for a few minutes, then once again when it hit the market, the stock available at that price was gone. Whoever it is has better access to the market than I.
