Pursuant to a Securities and Exchange Commission request, FINRA has agreed to make reported short sale trade data publicly available. FINRA will make one type of files available: Daily Short Sale Volume Files.
The Daily Short Sale Volume Files provide aggregated volume by security on all short sale trades executed and reported to a FINRA reporting facility during normal market hours.
Using the above link, I searched for CGRA and received the following data which perfectly matches the data in the OTC Short Report because it is from the EXACT SAME DATA SOURCE regardless of who runs that website.
