yeah, I think there is a troll trying to sell at 0.045 - 12000 shares at a value of $540. I've seen it in other stocks during a trading halt, bids all over the place and then they pull it before trading resumes - not sure if they are trying to be funny or spook people during the halt. I guess some people get off on that sort of stuff.
I bet that order will be lifted before trading starts again. I doubt someone would be selling that low due to knowing something. I can't imagine getting stung for insider trading for such a small trade would be worth it - as said just a troll!
