Oh I have a pretty good understanding of “short volume” and I am glad you clarified it from Shorting as that is a position as opposed to a momentary “marked” execution that short volume is.
That report you are linking to, FINRA has an explination/disclaimer for such a report stating that you cannot use it for the very purpose you are attempting to use it. No one is shorting this stock. That report is showing only how a trade was recorded for an instant in time while the MM provided liquidity for you to be able to trade at all. That report is not a explanation of ANDI "positions." Do some DD on trading in general. Start over on the DD board. They are most helpful.
