False - Short volume has nothing to do with equity Short interest.
Short volume each day is not shorting and is almost always covered in a few minutes. The volume that exists after the short time limit for reporting each day is reported as short volume 9not actual short interest, which is reported twice-monthly to FINRA as Equity Short Interest.
Glad I could help you learn something today.
Daily Short Sale Volume Files
The Daily Short Sale Volume Files provide aggregated volume by security for all short sale trades executed and reported to a TRF, the ADF, or the ORF during normal market hours for public dissemination purposes (i.e., media-reported trades). There are individual files for the volume associated with trades reported to each TRF (FINRA/Nasdaq Chicago, FINRA/Nasdaq Carteret, FINRA/NYSE), the ADF, and the ORF. There is also a file entitled "Consolidated TRF/ADF Daily Short Sale Volume Files," which combines the volume for trades in exchange-listed securities reported to the TRFs and the ADF.
