The bi-weekly short interest reports only reveal what wasn't covered many weeks behind the actual reporting date (week and 1/2 ago for most recent cycle).
The reporting date is easily a week behind the date these numbers hit the OTC Profile pages. It's very old data.
The daily short volume is current and doesn't indicate whether theshares were purchased that day, or when they will be purchased in the future (if at all...lol). This is the number that matters to me, and many others.
Short "Volume"s meaningless intra-day MM Order processing. That's their job...to process Buy-Sell orders.
