Good evening, kampman, arca is the market maker that has been supporting the bid on GRDH. They normally are not even listed on level II first thing in the morning, but then show up after the market opens. Not sure how many shares they have bought since the first of the year, but it has been a bunch. They are definitely loading up. Over 20x average volume and we close even is a little disheartening, but hey volume before price, right? I did notice that right before close, there were I believe 4 market makers showing bids of .55 which I took as a good sign. Something is sure going on, and who ever buys through arca has reason to believe it's going to be big.
