What that means Alan is that 46% of the trades today were done between different brokers. If every trader today used Ameritrade as their broker, there would be zero short interest because all trades would settle instantly.
Every trade that happens between different brokers like Ameritrade, and Etrade is marked short because it doesn't settle immediately because of the few minutes it takes to transfer the shares.
Have you ever wondered why your trade shows up in your account in seconds after you put in a buy or sell?
This is what these evil Market Makers do, they fill your trade before they receive your shares, then settle the trade minutes later to complete the transaction, but that trade is marked short on the daily report.
The daily short interest you rely on as DD is paid for by insiders of companies who are dumping shares that need an excuse for the ever falling share price. History is a bitch.
