I'm not bothered by bots. Of course it gives them a slight advantage or they would not do it. But in the end the fundamentals always win through for buy and hold.
As sandminer says, there is some advantage for us small fry. You can see what the bigger players are up to with their trading signatures on the ticker/course of sales. e.g they are accumulating, distributing, using vwap etc.
I imagine it would trouble me more if I was a daytrader or short termer.
