It's interesting though that the FINRA stats have varied between about 23% to 63%. You'd think that the market makers would have some more or less consistent percentage of that.

It's really too bad that someone can't invent some sort of electronic device that could track every sale, and then reconcile the sales with short positions left open, so that we could have that information every day. Instead, we have to rely the current technology which uses trained monkeys who pore over that information, and then FINRA releases that information, pooled together, for every two-week period. Gee, I sure wish someone could invent some kind of electronic device capable of figuring out that data in a timely fashion every day.

Since it computes information, if someone ever invents such a thing we could call it a "computer."
