""Can someone enlighten me as to whether today was a low volume or high volume down day?"
-> For any stock,a price rise doesnt happen overnight .It take the removal of free float from the resistance and this happens over months if not weeks . If price rises without the removal of free float then the rise would'nt be sustained as there's sellers in the background which hasnt been removed .I'm sure you may have noticed stocks jumping 30% + in a day but soon they come back to its previous level ,this is what happens when free float hasnt being removed , and played by the daytraders .
"Apparently it will make all the difference for tomorrows price movement. "
-> If you want to know what tommorow's price action for any stock will be then i suggest you to do some reading on candlesticks patters and VSA analysis .
P.S - If you really want someone to answer your question, next time you ask a question , include PLEASE in it and do not post just to get the limelight about this issue without doing your own research on some TA .
