nice observation, do you see the same 486 on ask? could it be an automatic sell that is occurring with the 25 mil shares used to pay a note, or could it be greene selling? interesting..
On the run up a few weeks ago, the ask did the same thing it is now doing... Often an ask of 100 - 500 shares at a time. Hit the ask and no change, just another 100 shares added to the ask. I started hitting the ask but made the order an all or nothing order for 1000 shares. That seemed to move the ask price. I knew that I wanted several thousand shares and didn't want to buy them 100 shares at a time...
