What the hell, I'm not trading right now so I might as well share one of the strategies I used. Maybe someone will make some money with it. I used to set up a scan and only watch size on the offer for NYSE stocks. Size only matter if it would step down every time there was a downtick. This would tell me that it was a large short-seller. Now I could either buy bullets and short in front of the short-seller or wait until that seller was cleaned up and then I would go long for a nice, quick profit. As soon as the short-seller was cleaned up and I made some money on the long side, I would keep my eye out for any strong movement downward because I knew that large short-seller would be back. As soon as he was back, I was shorting in front of him with my bullets. Does anyone use a strategy like this.
