vsisto, the reason I said all you need is the last price and T&S is because before the open book that is, more or less, all you had. Honestly, that is all a good trader needs. You can read the specialist' actions by seeing where he prints stock and/or if he offers the stock on a minus or plus ticks the stock. The T&S tells you everything from the bid and offer to where the stock is printing out. I wouldn't knock the Open Book until you try it. I stand by my statement that there is not a delay and if there is it is not 10-15sec., but to all their own. The reason I am set on this is because the bid size might quote 50,000, while the book says 17,500 and once people start selling you will see each order whack out a portion of the bid as it prints on the T&S. Then, whatever was left will disappear from the book, you see it on the T&S, then the bid disappears from the quote. Like I said, to all their own, but try it first. Regardless, I only use it once a stock gets close to the half or the figure, to find imbalances in the pre-market and to see who is offering/bidding stock of any size if I am about to buy/sell size. As far as Direct+, I hate it also. It is the worst thing on earth. I will be selling a stock and working it lower and some idiot mook trader will AutoX the stock and cause everyone to get scared and cover. I don't want an AutoX if I'm trying to whack out a bid or lift an offer.
