Does anyone know how to find data on short selling?
For example, I know how to find the daily FINRA short stats:
date short vol exempt vol total vol short/total ratio % short sold above NBB
27-Mar 7864 3735 13739 57.2% 47.5%
26-Mar 8111 5506 41261 19.7% 67.9%
According to FINRA 19.7% of volume were short sales (Wednesday) of which 67.9% we sold short at above national best bid (which to me is probably naked shorting), and yesterday 57.2% of volume were short sales of that 47.5% was also shorted at pricing above the bid. Usually there is no short exempt volume; when there is, you know there is a short selling frenzy.
 There is/was supposed to be a ban on short selling Weds and Thursday, since we opened 10% red Wednesday morning: shorting is banned for the rest of the session and the following trading day automatically (supposedly).
This does not seem to be reflected in the FINRA data
 Does anyone know how to relate the FINRA volume to actual volume? Total volume of 41,261 for example: where do they get that from when the volume was 7M on Weds?
