Source of buying on equities market

[illiquid]

Hi, I was wondering, is there a good enough method to determine from the pattern of volumes/price moves the source of stock buying. Either who was the major buyer at a given day: ETF/LO/HF/Retail or what type of investor was driving any particular move on the stock market.

it's confidential but sure, somehow one can figure that out. most are news-driven.
