RE:Games being playedalgorithms and AI infestation was going on for a few years now. But HOH is way too small for scalping a few cents of the trade. What you see is perhaps a glitch, maybe there was no bids at all, the posted bid price was perhaps the last trade - maybe something like that.
Even with big companies, intellectual help did not make a difference for investors as company health cannot be affected by it. IMO price movements became cleaner, there is less tax loss sell off or RSP buying frenze, it was all effectively quenched by bots.
