It's crazy how much 'movement' there is on the bid and ask, with no volume to make it change. There was a bidding war at 0.161, 0.162, 0.163, 0.164, and now it's back to 0.16 with out any volume hitting the bid. The ask moves 5-20k shares between 0.17 and 0.20 everyday, all day. Again with usually no trades causing the moves. Just MMs or retail playing with orders all day. Weird.
