Guys, intraday "short volume" doesn't equal "short interest," which is reported twice a month. There is plenty of discussion of what those RegSho numbers really mean elsewhere on IHub, and FINRA's own guidance on the subject has been quoted repeatedly. If I wanted to sell 100,000 shares of IMSC and my broker sent the order to a market maker, the sales would be done in pieces and each of the trades would be recorded as "short volume" because my shares wouldn't be journaled over to cover the "short" until the order is completed or the end of the trading day. I have personally seen days when my sales were the only volume in a stock (not IMSC), and it showed up as "short volume."
