I am trying to learn and understand how inflows and outflows technically work and how they relate to the underlying price and changes therewithin. for example SPY had net outflows during periods it increased in price and net inflows as it was decreasing in price.
how is this possible and how would it work? how could there technically even be inflows or outflows of $ if every transaction includes a buy and a sell, technically wouldnt it be even, ie if i buy spy at $570, someone must be selling it at $570 so there shouldnt be any money going in or out ?
\* reddit cut off the rest of my question:
and if that means simply when i buy its a net inflow of $570, why would the price move upwards on days where there are net OUT flows and move down on days where there are net inflows? i am not getting how this is possible.
someone help me understand this if you can , thanks.
