Shorts Exposed

[Dragonwing]

Exactly, it is one number, and the only way to join that total is to be marked as Z, C, or P

There's a few reasons for the variance of all the numbers

Certain OTC transactions (e.g., riskless principal and agency transactions where one member is acting on behalf of another member) are reported to FINRA in related tape and non-tape reports. Tape reports are submitted to FINRA for public dissemination by the appropriate exclusive Securities Information Processor (‘‘SIP’’), while non-tape reports are submitted to FINRA, but are not submitted to the SIP for public dissemination.

FINRA will not be including non-tape reports in either the daily short sale volume file or the monthly short sale transaction file. Accordingly, in those instances where the short sale indicator is only included in the related non-tape report, the short sale data published in the daily and monthly files may be under-inclusive. Similarly, the published figures will not include odd lots since these transactions are not disseminated to the consolidated tape.

Once the Daily Short Sale Volume File is made publicly available at the end of each trading day, FINRA notes that users of such data should not expect the daily and monthly data to reconcile because, among other things, monthly transaction data will include reporting through the end of FINRA transaction reporting hours that terminate as late as 8:00 p.m., while daily volume reports will only include volume reported during regular trading hours.

FINRA will not incorporate trading information into the daily short sale volume file that has not been executed and reported within the trading day. While members generally are required to report trades in equity securities to FINRA within 90 seconds, a firm could improperly delay reporting of short sales until well after the close, which would result in the under-reporting of over-the-counter short sale volume.

Further, FINRA will not retroactively apply ‘‘as of’’ and ‘‘reversal’’ transactions to update the daily statistics.
