Hal; I do taht by the seat of my pants, it takes some getting use to, it's when the tick , and the indexes go the opposite; the only way that can happen is when they artificially jack up the ASK/bid , in collusion .. Don't think for a moment they don't manipulate the bid/ask, and the entire market when they can. Did you see the spike at the very last min, well when you see those pronounced spikes it's not traders doing it, traders don't act like some school of fish all running in to buy or sell at the same time. There are tricks they pull with the futures too, and it can kick in program buying ( a mindless computer sees the futures up so it starts buying stocks and selling futures ) this should be out lawed within 30 min of the open and close of the market but each side wants to keep it as they both think they can win, ( that they are for the most part playing with other peoples money makes it a fun thing for them and not so bad when they lose )
We don't have timely data on shorts that one can use as evidence , while it would be simple for the exchanges to release on going short interest on a running basis, it would also mess up their racket so you won't find that. Old data is worthless , and the best I can do is get a feel for their habits , it's easy to miss if your not looking right at it. Jim |
