Sorry, SnS, for missing your post to me. Yes, I have noticed not just that day, but a number of times there seems to be a large buy order put in on the bid that stays there for part of the day and goes away if there is no trade at the bid after awhile. That could be someone who is trying to scare up a seller willing to sell at the bid and not at a price in the spread or at the ask. When he does not get a nibble, he cancels. The positive thing is that someone or a few people are interested in buying 30,000, 50,000 --the largest order I saw last month was 60,000--and have yet to get what they want.
Keeping things interesting. I, for one, want to see more news on revenue, orders, more distributors and so on. Right now, we are in an information void of sorts.
