thanks. i thought maybe you could track sales on an uptick versus sales at the bid and somehow average over the net price change. if the stock went down and all the sales were at the bid, and not at the uptick, then it would mean straight selling. if there were some way of figuring that the price was not going up [b[enough or down too much whatever these too much or enough's mean, then perhaps you could track it. sales at the bid in an upmarket mean no shorts, sales at the bid in a down market mean no shorts, and everything in between I guesss is a guess. I hear people saying oh its a short covering rally or oh its shorts killing themselves and driving the price down, but how do they know
