If I could clarify, then there would no longer a need to be referred to as "they" or "them"![]()
Well, what I believe is that the market is impersonal and at the end of the day it's simply a order-matching engine with orders going off against others, i.e., market orders crossing with limit orders. When market orders (demand) exhaust the available limit orders (supply) at a given level the market will move higher or lower. That's really all there is to it, regardless of the reason for that happening. Markets can move higher or lower on both high and low volume. Markets can be in equilibrium on high and low volume. Markets can gap, too, with no prices traded in between, i.e., no volume.
I'm sure traders, both retail and institutional gets "trapped" all the time, but I think they do it largely on their own. Mostly, I don't think anyone (they?) is trying to do anything to anyone, although I'm sure it can happen.
I may very well be wrong.
