Any market, though I am mostly referring to equities - 'In general' are one or a small few big buyers/sellers enough to give the market direction during high volume times of day? Once this period is over obviously it can stay, reverse, or continue. Since price has to move I just wonder if it is 'pushed' by the big players since HFT's are all knowing anyways, and they shake out the little buddy that chases like clockwork. The alternative I guess would be 'more buyers than sellers' but this seems like b.s. since when the market moves it moves and the 'opening price principle.' I have not worked for a big institutuon, and I am continually trying to learn more about market mechanics. Would appreciate any real insight here.
