Chartwatch, page-88

This is how it works: The shorters borrow stock from a holder that has dried up of retail money.
The price at which they borrow is say $2.00.
They buy and sell small parcels to themselves driving the price down picking up stop losses and putting the fear of christ into holders who then to dump their stock

They may drive the price down to say $1.00 if that is their number; and then cover their shorts at that price and make a profit on the difference, they can do this both ways.

Now think yourself lucky you have this info in your first post because it took many hard and battered years to learn this.

So the moral of the story, once the bots get in: get away.
