"This question always mystifies me, because in every case, the answer is, "Both." There are always equal numbers of buyers and sellers. That said, the way people answer the question reveals their bias, and that alone."

Well, practically speaking yes. One also needs to consider the banks of shares, and in many cases, phantom shares that may be there for purposes other than to sell or buy.....shares that are used to give the impression that there is great demand when what is desired is for the Asks to be able to exit into larger volume. Yes the share sold is the share bought but not necessarily out of simple supply and demand. However, we do trade what we believe.
