Its a program that runs to accumulate or sell off parcels of shares. By doing this in small parcels it prevents the sp from gaining or falling too fast.
Basically it can be used as a form of manipulation. I don't care what anyone else says.
You can't beat a bot.
Institutions use them and faster than you can place a sell or buy order, it will match what you have done to compensate so that the sp ends where ever the buyer/seller wants it to be.

In the case of ATQ, a bot has been buying regular parcels of shares leading people to think this is being accumulated. That theory is just one side of a coin imo.
