BOTS are automated trading programs used by institutions, which are programmed to buy and sell. They usually are associated with lots of trades during the day and are designed to get them in at average prices throughout the day.

Not good nor bad, but quite often are noticed when a stock has a small volume of sales, like WHE recently,

Just look at the small trades anywhere from one share up...Yesterday they bought 11 shares at close which made the stock close at 30c

Just another tool used by insto's, costs less than paying a person.
