Ok.
And what edge do you think you can have over machines that are basically making markets based on their current baskets/inventories and where the ES/NQ/YM are trading? In other words, even if you knew the exact algorithm by which these things were basing their trading decisions on, how would that make you a better trader?
What I trying to point out is that understanding the machine will only help you in programming another machine maybe try to do the same thing, but I doubt it would help you as a human being at all. The way you trade now is the only reasonable way, outside of technical analysis, that a human could trade.
There are only two ways to trade outside of arbitrage (statistical or otherwise), to take liquidity away from the maket and therefore pay the B/A spread (for whatever reason, breakout, etc), or to add liquidity by making a spread, which is mostly what computers acting as MMs are doing, except when they come in a buy/sell baskets for index arbitrage where they are then taking liquidity. The MMing is almost 100% the domain of well capitilized MMs.
People like Bright traders try to do pseudo MM type strategies like the Opening Strategy, or the Trade Through strategy but that is a huge patience game and is not for everyone.
What I am trying to get at is that, imo, very few of the players can play these games, although three people that I know of on ET claim to be able to trade stocks 100% by computer, and no one in their right mind is going to tell you how they are making money doing that (if they are, which is a big IF)
Most of the reason the markets seem so confused now is that there are so many different ways that stocks get kicked around by their derivatives, whether it be Futs on them, Futs that include them, Options on them, or ETFs that include them.

Interesting ... I agree that I have yet known one case where a small sized (i.e., not in the top 10 in volume) MM have tried to do full automated MMing. However, although one have no insight into the automated algorithms used, their behavior can be modelled for non-MM systems to be taken advantage of.
In my opinion, stocks have too many possible ATSs, but for single listed products, the automated system can only perform limited information hiding (unlike stocks, where smart splitting and routing is becoming a high art), making it possible to perform pattern analysis. However, such patterns disappear so quickly that the only thing that can take advantage of such a pattern is another automated system, one that must also maintain a sufficiently complex pattern database, complexity that is probably out of reach of most (if not all) individual traders.
Such high frequency data analysis and trading more closely resembles game theory rather than any finance theory or TA.
