Quote from NY0BScalper:
A lot of the time I trade based on discretionarily trying to interpret the order flow and because of my experiencing and good risk management, it works, definitely no silver bullet, and I find it analogous to the way you claim to use common sense and critical thinking.
However, sometimes - rarely, but sometimes - I see a raw pure edge, some stupid free money left on the table where I am the only person understanding the way the algos in a stock interact and can trade with really, really high accuracy... not being right 40% of the time and holding for 2:1, being right 90%+ of the time with 1:1, where if I posted on elite what I was doing that would die down.
One problem I've found, is when I get that real real edge, and it lasts a few weeks or a month, I tend to give back way too much of the money I made trying to re-learn to trade the old fashioned way - without an edge - with critical thinking.
Perhaps you have never experienced an edge in the form I described very vaguely above, but I suspect Szeven has something stupid like that... like he noticed that in stock XYZ whenever some program that shows 700 on BOOK ECN refreshing, but flashes pulling (i.e. you don't see the quote for a brief second but it comes right back, long enough to get the twitch scalpres out) with a certain unique time-signature, the program gets filled on shares, pulls for 3 minutes, then jumps back in on the the bid 10 cents higher than before... so if he notices that, he buys the shares after the program leaves, probably a ridiculous amount, all he can below 10 cents from where the bid was t he first time, where he doesn't really have a safe out, but he's relying on that program coming in, and because he has an edge, it does, and he can sell all he bought at a profit, and he only loses when the program comes back in but gets immediately filled by a seller, or when natural market activity pushes the stock against him to a point where he can't manage it.
I have no idea what the fuck he does, I'm just speculating out of my asshole, but it does seem like a reasonable explanation for such consistent P/L
