You aren't making any sense nor is anything you said relevant to the question at hand, namely "How can a print be a buy or a sell, when all trades require both a buyer and a seller?".Quote from Ebo:
Institutions are both buyers and sellers.....sometimes both!
Marketmakers just accumulate, meaning buy or sell small amounts of stock all day, and when they have enough accumulated 10K or 25K or any other number that makes you happy, they then reprint the stock to confuse you....... often out of sequence..... to confuse you even more!
This is done net these days, PLUS a very small commission as opposed to the good old days of 1999!
