A large share of US stock volume never touches a public exchange — it prints in dark pools, alternative trading systems, and wholesaler internalization. This page tracks that off-exchange volume daily for 5,500+ tickers, plus how much of it was reported short.

The name is a joke; the data is not secret.Off-exchange volume is reported to FINRA and published — it is not insider trading or hidden activity. A high short percentage means more of that day's off-exchange volume was marked short; it is not by itself a signal to buy or sell.
