i have noticed the same accumulation bot running on two gold producers i hold and some others. i suspect it is running on lot of other gold producers. in the course of sales posted below the larger orders are the trigger orders, then the bot buys 1/5 of the order and continues to buy roughly a 1/5 of it's last order until 1. this imo is very likely the same bigger buyer accumulating across a heap of our gold producers.
