Seems odd that someone had stacked 4 consecutive sell orders for 8,000 shares each between 3.15 and 3.18. Prior to that, yesterday morning when it started looking like it might push through 3.30 towards 3.50 on light volume, someone put on a large sell order which did the trick and pushed a few traders to bail and push the price back towards $3, again on light volume. Are these legitimate sellers that have no idea how to sell a stock trading thin volumes or are they holding the price down to accumulate as much as possible before the next up leg?
