Short volume is caused by normal market making transactions, and is only recorded on the initial leg of a Multi leg transaction. A good example is an "internalized order" in which someone uses a market order sale, which is picked up up by an MM and sold by that MM over the spread. Due to the MM not actually having physical custody of the shares it must be marked "short" by SEC Rule 200. Other good examples would be new shares from warrant, debt and note holders in accordance with SEC Rule 203 require marking such trades as "short" as part of risk exposure due to potential restricted legends not being removed and causing a trade rejection.

So let me know if you want to understand such reporting and why it occurs. The main purpose of the Reg Sho Daily is simply settlement rates from trade inception and nothing more. When combined with the FTD report one can use that information and conclude substantial short volume within a security if such substantial short volume exists with failed trades.

Anything else?
