it looks to be a pattern or trades adding to 200,000 shares.
i didn't see the depth prior to see how many people were unloading i.e 1 person unloading 200k or 8 people unloading 200k but this to me looks like these were orders in the buy queue.
seems like someone is still accumulating or am i mistaken?
