The existence of injustice seems to me an absurd argument for the creation of ever more of it.

That would be an outrageous injustice, heaped upon the preexisting injustice of the bailouts/handouts/stimulus. Just imagine the effect on people's thinking -- "Great, now I can go into debt over and over again, and have my more responsible neighbors forced to pay me off, again and again."...

These are all more or less the same thing. Unless the system in question doesn't use any numbers, in which case it's not quantitative. Said system might not be too profitable, though :D PhD's from the top 5 programs in either pure math or CS seem to have the highest odds of outstanding...

Incredibly, it's not obvious to you that your post is by far the most diseased and miserable in this thread.

If you're dissatisfied at $1M a year, I can't imagine that any multiple of that will suddenly leave you feeling fulfilled. And no matter how much you save during those 4-5 years, if it's in the form of real estate, stocks, cash, or fixed income, that savings is still more or less paper...

This article layers a ridiculous conclusion on top of misunderstood observations. What's it advocating, really? Bring back the "good old days" of high fees? The only area I see in which traders could harm value investing would be in using illegal insider information, which of course is...

Without denying that there are indeed many negative aspects of globalization, I've got to say that the absurdity of this post's pessimism gave me the best laugh I've had all day :D :D :D

Perhaps the market is just too efficient for you to earn a profit, given whatever methods/indicators/etc. are currently at your disposal. If it were manipulated or irrational, I think that there would be a profit opportunity there in itself, especially given the low slippage/high liquidity of...

Yahoo has data going back many years (how many, I can't remember) on many stocks; maybe Google Finance, too.

It's unclear; if they failed to locate once, they'll probably fail to locate 3 days later. And ET is known to "fire" clients they find annoying. And you might be forced to buy in at a bad time and/or price. On the other hand, if the symbol is on their publicly-available short list, they're...

In that case, you're going to have a hard time measuring cancels using Level II data. Or to put it another way, you'll be measuring the number of per-MMID-top-of-book cancels (since Level II only shows MMID top-of-book). You would need a full book feed such as TotalView to see atomic...

Depends on how you define cancel. The OP evidently defines differently from you (although I prefer your definition). With Nasdaq Level II, the top of each MMID is all you get. They could have 1000 bids below their best and only one shows. That's why they released TotalView...

I mean either the bid or the ask. Ultimately, I think this is handled on an Island order book basis (largely viewable under TotalView), and Level II is simply a slice of the big picture. My impression is that Nasdaq converted itself to a bigger version of Island when they bought Island...

I'm pretty sure that 0@0 MM quotes indicate a cancel and that the particular MM is no longer displaying a quote on that side. You might want to verify that with Nasdaq docs.

The exchanges also have lists (see nyse.com, nasdaq.com, amex.com). But they aren't always easy to parse.

1) Nothing is wrong with pre-canned strategies per se, but it's often hard to know if they work unless you use it for a long time. And even then, things can change, so be careful :D 2) No and yes. "Some people" make it out to be infinitely hard, i.e. impossible; but of course it's not that...
