I've seen those MM signals posted before. While I certainly believe there are signals between them, I just don't think that particular chart is accurate. Maybe It's just me, but I don't see any signals in there asking for the stock to rise, so the MMs can sell off their cheap shares.
I agree those tiny trades aren't real. But I've seen different types of signals, when a stock is actively moving by cents, and there's a small ask that reads something like $2.5101 or similar. I admit I don't know enough about the MMs to say what each signal is, but I do notice a trend that when a low number is in the 4th digit place, the stock may move down, whereas a high number like $2.5108 tends to tick the stock up. Particularly with 100 or 200 share quantities. I can't think of a legitimate reason for that type of bid when it isn't really partial cents but skips to an insignificant number.
Just my opinion, but it seems to make more sense than a list of signals that don't include a "bring the stock higher" sign.
Has anyone else noticed what I have?
