Hi, I never traded a stock on the Grey's before and with the SEC suspension one of my stocks is going to trade on the Grey's. Since this stock also trades there I was wondering if you, or someone else could give me some answers about this market, and more specific about trading.

Is it true that trades go thru ad random?
Lets say someone puts a bid in for 100k shares at 0.50, and someone else want to sell a 1000 shares at 0.001, is this possible, or do orders get handled from the highest bid, and if there is a lot of bid whacking then they might get to those 1000 shares sell order?
