On the contrary Don, I think that your statement is silly!
Level II can be quite intelligible for some traders. I have worked at prop. firm (now trading my own capital) where we traded exactly as momotrader described using Level II and limited charting. I can attest to the fact that it is possible to make a damn good living trading only what information you can interpret from level II. I was by no means the most successful trader in my firm and tend to use charts a fair bit but I traded with guys making six figures who used level II almost exclusively. For these guys charts are almost a nusciance! These guys get so immersed in watching the level II that they can visualize patterns without charts and become very good at anticipating moves in a stock!
I will admit, that for those who merely look AT the level II it can be "unreadable". But for those who look INTO the level II it can provide an amazingly clear picture to a stock's behavior. Looking INTO a level II is a skill and an art and it takes a great deal of time to develop the insight, but to say that it is not possible.... is in my opinion just wrong!
I will add one caveat to what I have just said;
the traders that I have described are able to use the information that they see in the level II to trade (ie. extremely short-term high volume scalping) because their commission structure permits them to do so. Having low trading costs (paying only pass-thru fees) allows these traders to change their positions quickly and often. Add to this the fact that they receive liquidity credits for posting bids and offers, and making large per share gains becomes much less important than for most traders.
So Don, while trading strictly from a levell II 'box' may be prohibitive for traders at your firm because of the commissions they have to pay to Bright, it is not impossible. Only in your world pal, step out of the Bright Trade box.
P.S. sorry if my ending seemed like a slam to Bright, it is not intended to be, but I feel that Don's answer is biased by Bright's business model.
