Tuesday you mean? Not really. Shows up to me as tons of selling. Over the rest of the day, algos were big buyers, dark pools net sellers. Not much insight from accumulators that day. Price was a better tell. (gapping down, but closing green with an engulfing candle)
Thanks for input. Yes, I meant Tuesday. I based my volume statement on at least one moment when over 100,000 shares were traded in a single minute. We had at least one spike that high and lots of other particularly large one-minute trading spikes. My working thesis has been that some big buyer(s) (institutions?) kept the Tuesday morning open dip from going as deep as shorts had hoped by loading up and this participation changed the outcome of the day. I imagine that algos were indeed big buyers as the day progressed, but I was really focused on the first hour or two of trading. It may be impossible to reliably quantify who the buyers were during the high-volume early trading on Tuesday.
