More interesting is why the purchase orders at usually at >=$1.0, and then there are sale orders at =<$0.999. Why someone would automate something to lose money so consistently? I guess this is what the author was calling out, not the numbers per-se. The numbers just point that the buy/sell are the same entity, human or not is irrelevant for the number. But the behaviour is the odd part.
