The moderator is correct to point out, when looking at Nasdaq market data, TotalView is what you should be asking for. To make sure people know the difference, Level II only shows ONE bid/offer from each firm quoting in Nasdaq (this includes both SIZE and BRUT). TotalView shows ALL bids an offers from every firm. Over the past year more firms are putting multiple orders into Nasdaq at the same time, and we have integrated all BRUT orders into TotalView, making this an important difference
The best stat to point this out is that, Nasdaq research shows that typically within .05 of the best price in Nasdaq 100 stocks, TotalView shows you twice the number of shares as Level II. That basically means if you're using Level II data you are trading with one eye closed. If you're looking for an entry or exit point at a certain price level, TotalView may show you that opporutnity is available where Level II would not. TotalView is also the fastest source of Nasdaq data, meaning having TotalView could give you an advantage in being first to the punch when you are ready to trade (especially if your strategies have been automated).
TotalView costs a little more ($5 per month more than Level II) but it should pay for itself with improved execution on one trade.

Quote from Avalanche:
level II is somewhat dated most pro's are using something called "total view" (nasdaq) its faster than level II and shows much more depth.
as to the usefulness question, its definitely useful but it varies widely as to how much according to how your trade.
the easiest example of its use would be the depth you see in total view on stock that doesn't trade but 500K-750K shares per day. The level II might show 1300 shares between you and the whole number, total view might show 2500 or 4000, whatever.
What is helpful is if you have 5K shares and its printing .06, then .05, the .04 and its THIN. Seeing that full depth gives you an idea of where the exit door is and allows you to lean on size or adjust the rate at which you can work an order or just get the hell out.
yes, orders can pull, they are spoofed, refreshed, hidden, etc, but its still additional information and over time you can learn to quantify it somewhat.
, but totalview is way better then the nyse openbook.
